Hey everyone, Kyle Troop here and welcome back to the channel. Today, as you can see, I have the Storm Concept [music] here in front of me and I would like to give you somewhat of a lengthy review about this ball. This ball is a game changer. I'm just going to say that right off the bat. It's a game changer. Little bit of spec talk about it. RG261 and differential 018. I do understand those two numbers may scare some people

away. Uh you don't see those numbers in pretty much any resin ball nowadays. Uh this is purely resin. There is no urethane in this. So it is allowed to be used in all [music] competitions. The reason why it has 261018 for the numbers is because of this cover. This cover that Storm Products created they say is the strongest cover stock they have ever created. uh they've never been able to use this cover stock on what I would like to say a normal

core or 25 040 because it's just going to flare out. It's just going to hook too much. It's [music] going to puke on itself. So, this is a very unique piece. She's unique. >> You're wondering probably what do I got going on with the three balls here. We have the same pin distance and the same mass bias distance. The only difference will be the distance the pen is from the center of my grip. First one here, four by 4 and a half. So

4 in pin, 4 and 1/2 in mass, 2 in from the center of my grip. Second one here, 4 in pin, 4 and 1/2 in mass, 4 in from the center of my grip. And lastly, 4-in pin, 4 and 1/2 in mass, 6 in from the center of grip. So, that's a little bit about the tech talk of this ball. I'm going to throw [music] all three. I am bowling on a 39 ft Don Johnson pattern. So, nice little medium

pattern to show you how they compare to one another. Show off maybe the lower pin, which I would expect to be a little straighter. This has been [music] my favorite so far. And the 6 in really allows me to open up the lane. So, let's hit the lanes and see how they go. All right, everyone. Here we go with the Storm Concept review. Like I said, I am going on 39 foot Don Johnson. Uh, I did hit all three of these concept with a 1000 grit Aberlon pad, so they have the same surface. And we're going to start pretty much with the lowest pen to center grip and go up from there. So,

the first one 4x 4 1/2x two. I would imagine this is going to be one of these smoother, straighter ones. Uh my goal with having the lower pin would [music] be for me be to be able to stay a little closer to the friction on some of these shots. >> All right. All right. There was a little left and first shot with the surface.

That was a little more about what I was expecting. Uh, got that one out a little bit. 39 ft. It is on the fresh. So, my break point is a little further right, but [music] we're going to throw this a few more times. Feel it out from around the same part of the lane. Nice and smooth off of the back. That was about one or two left with my feet. I'm going to move again. I'm [music] going to probably continue to move a

couple boards just so we can get into some oil to kind of really see the difference in [music] the mid lane and the backend reaction with these three different layouts. Moving a couple left. Probably going to bring my break point in a couple as well. >> I like that shot. I like it. I like it. That's probably about a good four left

off of where I did throw the first couple shots with it. I'm going to give it a little bit better pass, [music] but with it being 2 in from the center of my grip, it's not flaring very much at all. Uh so I shouldn't be able to open up the lane too too much with the lower pin to center grip. We're going to throw one more. We're going to move back to the right, even a little further than where we started,

just to see if this thing just really allows me to pump it or [music] keep it in front of me more with this lower pin one. Wow. All right, one more. I want to move a couple more. Right. See kind of where the limit is with this one. >> Off limits >> cuz I would say that speed was probably

a good mile an hour faster than the first few shots. So, we're going to move a couple more. All right. So, I would say the sweet spot probably anywhere from like 8 to 12 with my feet. You know, that was a little too far. And you can see it, you know, once they get offline, which on 39 ft, you're typically not going to play that straight with equipment most of the

time. So, we are now going to switch to the 4inch pin to center grip. And we'll probably start where we finished off with the 2-in [music] one and move left and see how much more overall motion we can get out of that. Now 4in pin 4 and 1/2 in mass bias to access point and 4 in pin to center grip from the same spot as the 2-in pin

to center grip. This is my favorite one out of all three. >> Kind of wonder, well, Kyle, you just struck from the same spot, same part of the lane as the 2-in pin. Yeah, but this one definitely kind of picked up in the mid lane a little sooner and almost bled off a little more because with the lower

pin, yes, it allows me to stay closer to the friction, but it also wanted to kind of get off line a little bit too early as well. So, [music] I'm going to keep messing around with this 4in one. I'm going to move a couple. Okay. Okay. Uh, was sliding 21 instead of sliding 18. So, that's about three left. I did get that kind of far to the right.

Let's keep feeling it out. Let's keep feeling it out. >> Just feel. >> So, as we're moving left on 39 ft, you can't just always continue to throw it right of five down the lane because sooner or later you're going to kind of get on the wrong side of the pattern playing in this zone. So, we're going to try and bring the break point in some. That was not a very good shot at all.

So, no matter which one I throw, we can't be spinning it like that. No, we cannot. That's what we're looking for. Actually kept my brake point in a little bit. That is almost a little more comfortable for me because I I don't feel like I'm fighting the fronts as much. I don't have to have [music] my ball speed up a little bit more. You know, that's around

my comfort ball speed zone. We don't have speed up there, so I can't [music] tell you the exact speed. All right. So, we're going to move another one or so off of that last one. You know, get this speed down into a comfort zone that we're a little more comfortable with.

All right. Mind you, 261 018. That's a lot of hook. That's a lot of hook right there. But now we have moved probably a good six boards left now off of the 2-in pin one. We're going to stay there. Just throw one or two more with this one and see if we go to the six. And it almost allows me to free it up a little bit from being this far left.

And it's still hooking. It's still hooking. We got the speed a little bit lower now, but you can definitely see overall just more motion compared to the lower pin because typically the lower the pin, the less the flare. So, another way you could say that, the lower the pin, the less overall hook that you're going to get out of the ball. [music] All right, one good pass here. That's money.

>> Money. >> Slid about 24. So, I might have drifted a little bit more there, but all right. We're going to now go to the 6-in pin to center grip. See the difference this one makes. All right. So, like we said, 4x 4 1/2x 6. Then way up there. Way way up there. >> Way way up there. [music] >> Let's see what happens.

That was about the same spot as the four. I might have got around it a tad, but I think we uh we found some hook with this layout. Definitely going to make a move off of our after our first shot with this one. We'll go and move another two. We seen lots of hook out of it the first time. But now, keep in mind as I continue to move left, the break point has to come left with me.

Sliding 27. Good nine to 10 boards left off of the first one. And you know, this does feel like I might be getting a little too far left with these, but you know, we're trying to show off a little bit. Trying to show off the different motions. I still like that because if you were [music] to tell me 261018, I feel like I'd probably be trying to play up five on, you know, no matter what the layout is. But I mean, I

probably wouldn't even be hooking it this much with some of our normal resin balls, so to speak. Jeez. Wow. This one hooks. Holy cow. I guess we keep moving. Keep moving. I don't know. Haven't really thrown this one too much. So, kind of learning [music] with you guys. >> We can learn it together.

>> I don't really know what the limit is on this ball yet. Sliding 30. All right, that might be the limit. You know, quick tip there. Headpin coming in front of the 10. You know, people just think, "Ah, the messenger missed." Typically, when it goes in front of the tenpin, the ball's coming in too late. It's coming in behind it a little bit. So, to me, [music]

I don't think I needed to move any more left because that was pretty good. And she kind of came in behind it. So, let's just dial in. No more experimenting. Time to just throw a couple strikes. I will say oil feels like it's getting down the

lane a little bit. You know, that's the other thing to learn with this concept is how it transitions the lane. You know, people think, [music] you know, oh, it's urethane. Well, you know, it's not urethane whatsoever. It's all resin. Bang, bang. I sliding 27. I was sliding like 18 with the first one. And it went through the eight pin. It's not like we're really working super

hard, but [music] so 6 in 6 in from the pin to the center of the grip. And as you can see, there's still not a whole lot of flare on this ball. This is 6 in. Remember, higher the pen, the more flare. So, that's still a lot of hook for that little amount of flare. And I think that's just because of the strength of the cover. [music] You know, they said it's the strongest cover they've ever used. We had a cover stock that was unusable, like unusable because it hooked so much.

>> But with the 261 and 018, you're not going to feel that strong cover right in the front of part of the lane. you know, the core allows the cover to get down the lane, which then gives you still a smoother reaction off of the back. Cuz even at this even at this 6-in pin, I still feel like it's nothing that's drastic off of the back end of the pattern. To finish the video, we're going to see how good I am. I'm going to just go 2 in, 4 in, 6 in. One

shot each. See what we got. That's all right. 2 in. Very clean. Not a lot of hook whatsoever. 39 ft. Probably wouldn't be using that one on 39 ft. But we get on some of these even shorter patterns. 37 Viper, short cheetah, wolf, you know, some of those other ones. I think that one's

going to really come in handy if I want to stay on top of it. Keep it in front of me. Now to the 4 inch. 4 inch. Let's see. All right. There we go. That was five left with my feet at the foul line. That's my favorite one. I said it at the beginning of the video. four by four and a half by four.

I feel like I don't have to play too far left with it. I also don't need to get caught playing too far right with it. Just a little happy zone in the middle. Maybe there's a happy tree. All right. And to finish it off with the big boy 6 in.

Well, so the 2 in got a weak tin, the 6 in 4 pin, and the 4 in. Perfect. So, two things from the video I want you all to take away from this. One, concept is a game changer. And two, I hope you can see how you can change the reaction of the bowling ball by just messing with the third number in 2 LS. you know, having the same pin distance, the same mass bias to pap distance, you know,

just moving that pin up and down 2 in 6 in really changes the motion of the bowling ball. So, thank y'all for tuning in. Shout out to Jtown Striking Spare here for letting me do this video, show off the concept, where to get a concept inside.com. I'll see you on the site. Peace. [music]

Performance Analysis

Testing revealed the Storm Concept delivers surprising hook potential despite conservative RG specifications (2.61 RG, 0.08 differential) that typically indicate lower-hook characteristics. On a medium house oil pattern, independent reviewers observed that the reactive pearl coverstock absorbs oil unusually fast—showing minimal oil tracking after the first shot compared to urethane alternatives—yet maintains strong angular motion downlane. The ball demonstrated a smooth, controllable reaction when thrown from the right side of the lane (around boards 17–23), with consistent hook through the pin and strong carry. Reviewers noted the coverstock appeared to shed factory grit relatively quickly, transitioning from a dull finish to a smoother surface as play continued, which may affect early-session behavior.

On medium-to-heavy oil conditions, the Concept showed more measured motion rather than an aggressive backend snap, positioning it as a complementary option to heavier benchmark pieces rather than a replacement. When moved into heavily oiled or fresh patterns, the ball’s aggressive middle-lane oil absorption became a limitation—it struggled to create significant backend response when carrydown hadn’t yet developed. Testing suggested the ball performs best when oil is still present in the midlane, making it ideal for tour conditions where patterns remain more uniform. Comparatively, independent reviewers found it offered cleaner midlane read and more backend energy than some urethane-style alternatives, making it a legitimate option for bowlers seeking a reactive pearl with smoother motion characteristics and predictable ball reaction.

Who Is This Ball For?

The Storm Concept is best suited for rev-dominant bowlers and tour players seeking a secondary reactive option that doesn’t duplicate coverage already in their bag. Its smooth, controlled motion and efficient oil absorption work well for bowlers who prefer finesse over aggression—particularly those playing fresh or lightly-oiled house shots where the ball’s gentle shape won’t overreact. The moderate core dynamics make it accessible to bowlers with moderate-to-higher revolutions who want predictability without sacrificing performance.

This ball will appeal less to low-rev bowlers or those bowling on heavily oiled sport patterns, where the Concept’s inability to create dramatic backend reaction becomes apparent. Similarly, bowlers seeking a workhorse heavy hitter may find it too controlled. However, for competitive bowlers building a well-rounded arsenal or tournament players needing a “tweener” option between their benchmark pieces, the $189.95 price point makes it a sensible addition that delivers genuine performance benefits on the patterns where it excels.

Bowlers Say

Bowlers say the Storm Concept delivers urethane-like control with better continuation than traditional urethane balls. Its ARC Pearl coverstock provides early, smooth midlane read while maintaining energy through the pins. Most effective on shorter patterns, sport conditions, and when controlling over/under reactions on house shots.

Bowlers frequently mention:

Mike Walker Feb 16, 2026

Core - AI Core Radius RG - 2.61, Diff - .018 ARC Pearl Coverstock Layout 3 3/8 x 4 x 2 The Concept maintains continuous motion and has strong hook through the pins. I felt like the Concept resisted the tendency to roll forward. It seems very different to what is out there today. It is smooth but acts like urethane and eliminates the noise about carry down like urethane. Out of the box I bowled on a typical house shot pattern. I was uncertain on my expectations after a few shots I was mixed on the ball reaction and hit the surface with 800 abralon. First day in league with the new finish, I shot 711 and used the ball for all 3 games with minimal movement. I have had the opportunity to throw the purple and black ball in the past and the Concept has a better down lane finishing result. I feel this ball has predictable motion with consistent carry through the pins. As a pro shop operator, I feel the Concepts cover is tunable for all types of bowlers and lane conditions to definitely achieve their expectations. Whether you are a slow roller or high rev rate player, the Concept can give the desired shape and results on all conditions. Mike walker Anne Marie Duggan’s Pro Shop

The Concept made me scratch my head at first, 2.61, .020 Diff and 1000 Grit Surface on a Pearl Reactive Coverstock. I watched the videos at the seminar when they were comparing it to the Pitch Black, Level and IQ Tour but was not really sure if it would be a ball that would fit me. After using it on the fresh at a tournament, I can honestly say this was more impressive than just watching it in a video. I am very tempted to try it on a league night just because well why not. If you are a Level owner I think you will like this ball as an addition to it.

KP_Bowling Feb 18, 2026

NEW MOTION STRIKES! This one is going to fill a gap that we haven’t seen yet. Stronger than a 78U with more down lane motion. Good shape but still controllable. Personally feel like for harder tournament patterns this ball is going to be in play A LOT! Very continuous through the pins, controllable through the mid lane. Do yourself a favor and put this ball in your tournament bag!

Tanner Feb 18, 2026

I drilled this ball 90x4x70 and it rolls just like a good urethane ball. I cant wait to see it tear up some short patterns. I would recommend drilling stronger if you intend to use it for house shots.

Duane E. Feb 21, 2026

I really appreciate the Storm Concept. I have never really been able to through Urethane in the past effectively. I always had to rely on surface and big hooking balls to control the downlane motion. That could lead to some carry issues. Then the concept came along and made me a believer. While I don’t think it is a ball that I would normally use in league, I gave it a try. It allowed me to play to the right and not overhook downlane. This surface really digs in and the ball does not flare much. I recommend drilling with stronger pin to PAPs this will help the ball flare and give you fresh coverstock to roll over. Where this ball really shined for me is on the 36foot sport pattern my league is bowling on. I am able to play around 5 and have some miss area. This ball really has good continuation where urethane would be a flat 10, the Concept knocks them down. I am really pleased with this ball.

TESTING ENVIRONMENT Type: Lakes Bowl House Shot BALL: Storm Concept Coverstock: ARC Pearl Core: : Radius Finish: 1000 Grit RG: 2.62 (14 Pounds) Differential: 0.019 (14 Pounds) MB/PSA: NA (14 Pounds) ME: Right-Handed Tweener Speed: 14-15 mph Rev Rate: 220 Layout: 40x4x40 The Concept redefines how core and cover combinations tackle challenging lane conditions, delivering a level of control and consistency that reactive balls alone often can’t achieve. Its ARC™ Pearl Coverstock acts as both the engine and the tires, gripping the lane to create continuous, predictable motion through the pins while the Radius Weight Block keeps the ball on line without locking up. Designed for situations where bowlers traditionally reach for urethane, the Concept shines on short patterns or flat, demanding conditions—anywhere you need a smooth, controlled reaction rather than a sharp backend hook. The Concept maintains consistent motion across the lane, carrying through the pins for strong, lively action. Designed as a two-piece ball with a thick resin shell, the 14-16lbs combine the smooth, predictable qualities of urethane with the versatility and driving power bowlers expect from a modern reactive ball. Don’t just take our word for it—watch the Concept in action and see how it delivers urethane-style motion with unmatched consistency, control, and confidence. Now onto my review portion of this ball. When this was released I just thought I will hold my thoughts until we put holes in it and see it for myself. Urethane-style motion balls rarely look good for me due to the low revs, but this was different. With the LEVEL I would hit it with 500 and it rolled well for about a game then just got super lazy, but that is not the case with this ball. The quick oil absorption makes this ball have a footprint on the lane and getting the ball down lane is easy, just have to remember the ball motion will be smooth to the pocket. When testing this ball against others I would be trying to get this ball up the third arrow and when I got it right it was very light in the pocket.

TESTING ENVIRONMENT Length:45 Volume: Med - High Type (THS, Sport Pattern etc):THS COMMENTS Core: Radius Cover: ARC Pearl Finish: 1000-grit Abralon RG: 2.61 (15) Diff: 0.020 (15) ME: Right-Handed Tweener Speed: 12-13 mph Rev Rate: 315 Axis Tilt: 14Â° Axis Rotation: 74Â° PAP: 5 1/8 R 7/8 Up Ball Layout: Pin Up and right of Ring 4 1/4 X 4 1/4 X 2 VLS The New ball that's out to end the Reign of Thane is a SPI Lab line release called the Storm Concept. This one is a very interesting, novel concept (heh). Storm developed a new cover called ARC. This is a cover which mimics Urethane motion but is reactive. In fact it features the fastest oil absorption of any cover storm has used. This strong cover creates so much motion so early that it necessitated a weaker core inside. If you thought it was impossible for a ball with a .020 differential to give you so much early read this ball will teach you otherwise. I tested the Concept on a condition that usually weeds out urethane shapes pretty quickly. Our house pattern when it goes through transition usually makes urethane balls unusable pretty quickly. Our pattern is long but the front of the lane opens up faster than the back because of friction thats built into the front panels. So the early balls get too early pretty quickly and when you force them through the front they don't retain the energy to go through the pins. I had better luck in this aspect with the previous Lab line release The Level. I had high hopes for the Concept to be an improvement on what I saw. The ball did immediately give me the same issues that urethane always has. Covering any amount of boards on this particular surface the ball lost energy pretty quickly. It wasn't an automatic 10 pin or worse the way urethane is, it was 50/50 on carrying shots from this angle. That's about what my level did. I did notice that this had a unique shape compared to the level. It did seem to both read sooner and give a little more motion in the back-end. I think this is because despite reading sooner than the level, it didn't get forward quite as fast, keeping a bit more of a round motion. When I moved a little right and upped the speed I really liked what I saw. With actual thane I couldn't do this in the transition because there was no way to force it through the front with my ball speed and all the friction to the right of this pattern. Not only could I used the Concept here, it gave me much more area than I expected when I did. This gave me a great indication of what I've heard from the guys who have tested this ball on the conditions you usually match urethane with, this ball is a good transition piece because it continues better than traditional urethane when you have to play angles with the friction. I think this one is going to be a hot ticket for people bowling on tournament conditions, and for power players and lefties on pretty much everything.

For the longest time, we’ve been asking when Storm will release a urethane or urethane like ball with the universal success of the Pitch Black. The IQ 78U has done very well, but it is clearly earlier and doesn’t do much downlane. That red ball works well on the fresh when the backends need to be controlled. But for me as a one hander with medium rev rate, I really couldn’t open up my angles at all with the IQ 78U and by the end of game one I needed something with more downlane motion. Looks like Storm has done it. Coming out of their SPI Lab is the Concept. It’s not urethane, but it’s urethane like motion. They took the strongest, fastest absorbing reactive coverstock, ARC, and pearlized it so it won’t be too early. The ARC Pearl (1000 abralon out of the box) grips the lane to get the ball to slow down like urethane. That cover is wrapped around the very low dynamic Radius core (for 15-16 lbs balls). That core is high rg (2.61) so it won’t start too early given the massive strength of the cover. And, it is only 0.020 dif, so it won’t flare much making it a very controllable, but continuous motion (not get forward too quick). It also means layouts really don’t dramatically change the ball motion. The end result is a controllable, predictable motion that is urethane like, but does allow more open angles. For players who don’t have 500 rev rate, it gives them something to go to after the IQ 78 runs out of gas before being forced into true reactives. The Concept is an innovative idea which achieves exactly what it was intended to do- give urethane-like motion that bridges the gap between urethane and reactive. Storm even reduced the # of logos on the Concept in response to feedback from bowlers that the ball hopping over the labels as it rolls down the lane caused inconsistency in ball reaction. Once again, Storm proving why they are The Bowlers’ Company. I drilled mine 4 x 4 x 2 (4” pin to PAP, up 2” from the vertical axis line (VAL)). So far, I’ve only thrown it on a house pattern where it’s a little over under, but that’s not what the Concept is made for. It’s part of Storm’s new Tournament Series- balls intended for flatter, tournament patterns. I can’t wait to throw it on PBA regional patterns this season. The early returns from the PBA tour have been nothing but positive. Every high level player who bowls tournaments should have this ball in their bag.

Layout: 4 x 5 1/2 x 1 Surface: 1000 Abralon Rev Rate: 470 Grit Tilt: 13* The new Concept is the next iteration of the Storm Lab Series. It includes brand new technology from both the core and coverstock. The new Radius core brings a very unique combination of core numbers that is not found typically in a stronger resin ball. The RG of 2.61 and differential of 0.020 is normally found in entry level resin type balls. The brand-new Arc pearl coverstock is extremely strong compared to typical coverstocks but creates a very nice and smooth arc with great continuation. I tested this on my typical house pattern. My lane surface although newer, has a lot of earlier friction on it. On the fresh, I saw pretty early hook but saw continuation through the pins. Unfortunately, with the added friction, the continuation lasted for about 5 shots before it became too early and smooth leaving the 2-4-5 from the ball losing energy. As I moved into the middle part of the lane and more head oil, I saw the good continuation again. I did have to get softer with my speed in order to see the hook from left to right. At the box surface, unless there is a lot head oil, this will get tough to use for a long period of time. As a result, I wanted to add Power Edge polish to see what the difference would be. As expected, I saw a lot more length and no issue getting through the front of the lane. However, the continuation became less as it did not slow down in the backend as much as being dull. I was able to move about 5 boards right and be much more up the lane to get to the pocket consistently. When I was close to the dry enough, I was able to have great carry. The only pit fall I had was when I missed right into the friction early. It would read the friction super quickly. As I moved in to the middle part of the lane, I saw too much length initially with the Power Edge. Once I softened my speed, it gave me great continuation again and gave me area left to right on the lane. I think for normal lane surfaces, the Concept will be better at a duller finish. I would likely change my surface to 3000 instead of power edge to get a little more midlane roll so I would not have to reduce my speed as much. Compared to the level, I found it to be slightly cleaner and much more off the spot. It wasn't quite as lazy as the level was for me especially throwing it left to right. I would recommend the Concept to someone who wants to have ultimate control on the fresh with some decent continuation that won't have to worry about the ball over hooking a lot. I would also recommend this to someone who loves the urethane balls but wants to upgrade above a Pitch Black or something comparable. The Concept is also legal for all levels of play due to it being resin and not urethane. The concept in my opinion would have more usage on tough lane conditions over house conditions. My opinion is that there are better ball options that are more true resin based for house conditions. For tough conditions, this ball will come with me on a wide variety of lengths. I think it takes surface changes well and the high absorption rate stops it from lane shining as fast as typical resin balls.

Storm Concept Coverstock: ARC Pearl Finish: 1000 Grit Abralon Core: Radius (14pd.) RG: 2.62 Differential: 0.019 Layout: 4 ½ x 3 x 4 - 2LS Layout Extras: 2 1/8 Finger Depth, "X" - 4 1/2 D and 1 Inch Left Tester: PAP 6 1/2 R, 1 1/4 D Review: The all new cover/core Concept is an absolute hit on most typical house conditions and short oil patterns. There has been a lot of misinformation out there regarding urethane, urethane options and blended type balls in this category. The easiest way to combat such information is that these type of balls offer early read of the lanes and control type reactions. This works well for over/under type conditions and also shorter modified/sport patters. The Radius core is designed to respond slower to friction providing the bowler maximum type control. The Arc Pearl coverstock is what stands out on this ball. It absorbs oil rather than pushing oil which allows the player to stay in the Concept much longer than traditional urethane. It even absorbs oil much faster than the previous Lab Series ball the Storm Level. In addition, the Level for me fell a bit into the traditional urethane look so it has been overshadowed by my Storm Pitch Black and Storm Fast Pitch. The RPM coverstock is not as good as Arc Pearl in my opinion. Recently, we changed my Level layout to see if we can see a different type of reaction. I plan on continuing to see what the Level can do as well. Especially since I enjoy urethane on a wide variety of conditions. Pro Tip: For those that traditionally tend to dislike urethane or urethane-ish offerings, don't hesitate to surface your new ball to a higher grit like 3K or 4K than gradually bring the surface down to your 1K or 500K grit. The reason being most bowlers dislike the early motion of the ball oob and give up before letting the lane shine and peaks of the ball to settle in a bit. If you have had this experience previously give the surface suggestion the "good old college try". I think this pro tip might just work for you. When the initial announcement came out from SPI regarding the Concept I was extremely excited. The Concept is the type of ball a large number of bowlers can use. I even recently drilled a second Concept to match my urethane offerings. The diversity in both balls will likely be enough to carry both to wide range of tournaments. I highly recommend the Concept.

Storm Concept Coverstock: ARC Pearl Reactive Finish: 1000-grit Abralon Core: Radius Weight Block RG: 2.61, Diff: 0.020 (15 lbs) VLS Layout: 4 1/2 x 4 x 1 Dual Angle Layout: 45 x 4 1/2 x 15 PAP: 5 3/16” right x 5/8” up Rev rate: 400 rpm Average speed: 16.5 mph Location: Prairie Lanes, Sun Prairie WI Pattern: Medium volume THS The new Storm Concept is the next release in Storm’s SPI Lab Series and is a new ‘concept’ in bowling ball technology. Designed to provide a urethane-like motion that is consistent and controlled but offer more continuation on the backend like you’d expect from a traditional resin bowling ball. The specs of the core and cover are something typically reserved for entry-level balls, but the new ARC Pearl reactive coverstock is extremely strong and essentially forces the ball to continue hooking through the pins. I have never been much of a fan of urethane motion, it’s a shape that just doesn’t fit my eye. I drilled my Storm Concept with a stronger drilling that puts the pin closer to my vertical axis line to help give the ball more response when it hits the dry boards. I’ve been impressed with what I’ve seen thus far. It has given me a urethane-like ball motion in the front and middle part of the lane that is smooth, controlled, and stays on line. But unlike urethane, the ARC Pearl reactive cover gives it a little extra kick on the backend, which is something I don’t get out of urethane bowling balls. When compared to the Level, I have been able to play nearly identical lines with the Concept. However, with the Level I get a light mixing strike or often leave weak 10 pins, but the Concept finishes a little harder on the backend and is higher flush in the pocket. The Concept definitely deserves a spot in any tournament bowler’s bag – especially those that struggle with urethane motion. For me, it’s the ball I’ve been looking for to help bridge the gap of urethane control without giving up downlane motion that urethane lacks. Chris Pollentier Storm Products Pro Shop Staff
