900 Global Cove Performance Test

TESTING ENVIRONMENT Type: Lakes Bowl House Shot BALL: 900 Global Cove Coverstock: RB 85 Hybrid Coverstock Core: : Magna A.I. Core Finish: 4000 Grit RG: 2.50 (14 Pounds) Differential: 0.043 (14 Pounds) MB/PSA: NA (14 Pounds) ME: Right-Handed Tweener Speed: 14-15 mph Rev Rate: 220 PAP: 5 7/16 Right 1/8 Down Ball Layout: 50×4½×50 Cove is one of the two newest releases from 900 Global. At the time of testing this ball I found it to be the closest to the Hy-Road 40, but the Cove was a tad stronger. Coming in with a 4000 surface allows this ball to save the energy for the reaction you are looking for to be strong off the pattern. I started going up 5 and kept moving left and after about 10 more boards the ball was maxed out and had to go to something a little weaker. That's where the Ember will come into play where the Cove stops.

900 Global Cove Coverstock: RB 85 Hybrid Reactive Finish: 4000 Abralon Core: Magna A.I. (14pd) RG: 2.50 Differential: 0.043 Layout: 5 x 4 x 3 7/8 - 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 Cove features the new Magna A.I. Core. What you will see right away is that the Cove is smooth and well balanced with the RB Hybrid coverstock giving the Cove slightly more pop down lane as compared to a prior 900 release the 900 Global Xponent. At the time, the Xponent was highly regarded in the arsenal but a bit overshadowed by some other SPI pieces. However, the Cove has had a hot start during trade show season and testers are really liking results. The Cove comes with a hybrid coverstock, finished at 4000 Abralon. You can expect a good benchmark type of look from the Cove. The Hybrid coverstock will not hook to early and after a few games will settle down nicely. I tested the Cove out on THS and after about three games rolled it on the Don Johnson (40') pattern. The ball is very predictable which is the true strength of the Cove. In my opinion the Cove goes through the pins a tad better then its predecessor two generations ago the Ordnance C4. The Cove will be a great option as a starter ball out of the bag.

900 Global Ember & Cove – SPI’s Latest Additions Deliver Versatility and Precision The 900 Global Ember and Cove are the newest additions to the SPI family, and both bring unique motion characteristics that fill key gaps in any competitive arsenal. I drilled both at 4.5 x 3, and despite sharing a layout, they each offer distinctly different shapes that I was looking to add to my bag.

I drilled the new 900 Global Cove to be a middle of the bag option, and that is exactly what I got! I drilled this new ball with the pin above my bridge and the CG in my palm to give the most control possible. Naturally i think this ball is super controllable, but adding a controlled layout helped it even more. This ball is the perfect ball to start with if you plan on bowling leagues this fall. The brand-new core/cover combo gives you a unique shape compared to the rest. I see this ball fitting in the "RockStar" area of the bag. 10/10 from me!

The Cove might be one of the smoothest balls I have thrown out of box. The Magna AI Core definitely seems to give the ball more stability. I was able to play around 5 on the fresh and it wasn’t too jumpy, just read and got to the pocket pretty consistently. This ball should come in handy around here with some of the house shots that are put out.

Cover: RB 85 Hybrid Reactive Core: Magna A.I. RG: 2.49 RG. Diff.: 0.044 Finish: 4000-Grit Abralon 900 Global’s new Cove is a Hybrid Symmetrical piece that is good for Medium-Heavy Volume patterns. PAP is 5 5/16 R 1 3/16 Up. Rev Rate: 400. Speed: 16.5. Drilled this piece with the Pin up between the fingers and CG kicked out 1” from the palm. I threw this piece on a left over house pattern. Out of Box ball motion started in the mids with a smooth shape on the backend. I compared this to the Zen 25 and Sublime Focus. Zen 25 was 4-4 more. Sublime Focus was 2-2 more. This piece fits between the Zen 25 and Ember. This piece will be good for all types of styles. Check Out the Ball motion Video on my Facebook Page: https://www.facebook.com/share/v/17AbTfirAA/

General bowler information: Right-handed stroker Release speed: around 16 mph Rev rate: approximately 240 rpm PAP: 4 1/2 over, 1/2 up Here's a look at my 900 Global Cove. Video was shot on the house pattern at Cedar Lanes in Sandusky, OH, which is 45 feet on 60+ year old wood lanes. The core shape is the new symmetrical Magna A.I. core, which features a low RG (2.49) and medium-high differential (0.044). Wrapped around this big engine (core) is the brand new RB85 Hybrid coverstock with 4000 Abralon finish, designed for smooth and continuous motion. Mine was drilled 4 x 30, similar to my !Q Tour and !Q A.I. I hoped for this to be a “ball up” from those !Q’s. With the box finish, this is a LOT more ball than an !Q. Moves and release tweaks helped a little bit, but the reaction/carry was below average. So, I decided to give this ball a light coating of Storm 2 polish. With this change, the ball got the breakpoint more easily, yielding a stronger but still controllable backend reaction and good carry. At 2:25 in the video, I threw two shots with the !Q Tour which had a similar reaction, and I finished with the Cove. Link to the video: https://youtube.com/shorts/tsm8Uk8txL0 Always keep in mind that if the reaction of a ball out of the box isn’t what you’re looking for, it’s very easy to change the surface by sanding or polishing. This simple step may give you a new outlook on that piece. Grab this one from your local shop and Bowl Up a Storm! #stormnation #900Global #nextgenproshop #bowlifi #willsnation

I drilled up my COVE with a 5 x 4 x 2 which is a standard layout for me on smoother pieces. I left it box finish (4000) to start for a reference point. I compared it to my SUBLIME FOCUS and ZEN25 on a couple of conditions. The COVE to me was a little less than my FOCUS and a little earlier than my ZEN25. The marketing of the piece by 900 Global is spot on as you cannot go wrong if you are looking to plug in a middle of the bag piece. One thing I did notice was my COVE was very smooth at the breakpoint. My FOCUS could get sideways quickly and the ZEN25 definitely was sharper on the backend of the lane. I always thought of my FOCUS as a "poormans" PHAZE II but the COVE is close to that smoothness. With only a 4000 finish on it at the factory, the COVE did lane shine quickly. I touched it up with 3000 wet to give it some of that giddy up and it was like it came out of the box again on how it gripped the lane.

Layout: 4 1/2 x 4 x 2 1/2 Surface: 4000 Abralon Rev Rate: 470 Tilt: 13* The brand new 900 Global Cove brings a brand new core and coverstock combination in the 800 series lineup. The Cove uses the new Magna AI Core which is symmetrical to bring a low rg and medium differential that has not been in the line since the Xponent. The coverstock is the new Hybrid S85 which offers a quite of bit of control with ample continuation to use as more of that benchmark type ball. On my 44ft typical house pattern, the Cove matched up really well on the fresh as expected. Its controllable nature allowed the ball to read the front and middle parts of the lane fairly well while not trying to be angular downlane. This is the ideal ball motion for most fresh conditions. I was able to use this ball a little straighter than most other balls in the line on the fresh but was certainly not as forward as a urethane type ball. As the lanes transitioned and I had to move to the inside part of the lane, my carry became a little hit and miss. Its control aspect became a little too controllable at times and I often left the corner pins. A change in hand position to add axis rotation allowed the ball to get down the lane a little further and give more angularity down lane which allowed me to continue striking more. I was actually surprised how strong the coverstock felt on this Cove. I think it will be a nice benchmark piece on a variety of conditions where the lane surface isn't great. It will still be a step below the Sublime Focus in quick comparison as the core and coverstock are noticeably weaker. The cove would be most ideal for those bowlers who like controllable ball motion and those who like to play straighter up the lane. It will be best on fresher lane conditions or a ball down from the Sublime Focus. Shining up this ball will give a little more length and backend but will still be pretty controllable overall.

Cove, along with Ember, adds a whole new dimension to the SPI lineup! I personally have really missed a mid-diff symmetrical option for those medium house shots and older lane surfaces where the big stuff just doesn't store enough energy. The Cove, with it's hybrid coverstock, creates a nice mix of traction and downlane continuation. Honestly, this ball hooks more downlane than i anticipated, which makes it more usable than other symmetrical balls with smoother covers. This ball fills a much-needed gap for me, along with the Ember, and they are both gonna round out my league bag nicely! You don't wanna miss this dual release! The perfect 1-2 punch. -Chase Valenzuela

Length: 41' Volume:Medium after league Type:THS Ball Speed 15.5 mph Medium Rev-rate 285-300 Playing the track: UP 10 :) COMMENTS Prepared for Anything! 900 Global latest 1-2 punch in the form of a Hybrid (RB89) and Pearl (RB85) covers wrapped on the new Magna A.I. Symmetric core will define your benchmark arsenal for the upcoming bowling season. My layouts are: Cove - pin down under bridge for control on the fresh Ember - Pin above ring for the strong backends and transition My Cove at 4000 was sluggish and more forward at box condition. A light buff with Power Edge provided the much needed power retention and allowed the cover to be more responsive at the breakpoint. This compared to my pin down Sublime is a similar shape with more length and usability in league. My Ember was next up after 1.5 games. 3 board move left to open up the fronts and watched the Power Edge polish push the to its happy spot. While ignoring some friction my layout still offer myself control at the breakpoint with continuation thru the pin deck. You basically get 4 balls out of this combo before of the versatility in cover adaption. This is possibly the easiest 2 ball arsenal choices I have ever had to start league.

Rev Rate: 340 rpm Avg. Ball Speed: 14.5 mph PAP: 5 1/2" x 1/2" ↑ Layout: 4 x 4.5 x 4 The 900 Global Cove has been a great fit in my bag because of how dependable and smooth the motion is, no matter where I line up on the lane. The Magna A.I. core gives me a really steady roll, and paired with the RB85 Hybrid cover, it digs in just enough in the midlane without losing energy too early. What I like most is how continuous the motion is—it never feels lazy downlane and always drives through the pins with confidence. On medium to heavier oil, it’s the type of ball I can pull out first and trust to give me a true read, making it a reliable benchmark option that I keep coming back to. I opted to polish my Cove so that it fit as a ball down from the Ion Pro.

The Cove is one of the newest additions to the 800 series at 900 Global and it’s been impressive so far. If you’ve seen any of the marketing over the summer from 900 Global, they released a two-ball punch with the Cove and Ember and the results have been great. Both balls are symmetrical and the Cove is designed to be an earlier-reading ball while the Ember is designed to provide more length and a quicker response time. The Cove offers a hybrid coverstock, an RG of 2.49, and a differential of .044. I’ve drilled one so far and really like it. I mapped it out as 5 x 5 x 2. This puts the pin above my ring finger and the CG is stacked. I also took a bit of the surface off by using a 3000 pad and water. The centers around me have quite a bit of early friction so I wanted the Cove to still get through the front of the lane and not burn up too early. I’ve been able to use the Cove on multiple patterns and surfaces with success. I think the Cove compliments the Origin EX, Ember, and Ion Pro Solid extremely well, so if you’ve drilled those, I think the Cove would be a great addition to your bag. Go drill one!

The new 900 Global Cove features an all-new core design, the Manga A.I. core. The coverstock is the Reserve 85 Hybrid coverstock in blue/sand/teal to add shelf appeal. At 15 pounds the Cove has an RG of 2.49 and differential of .044. I drilled my Cove 5x5x2 which puts the pin above my bridge. The Cove’s cover helps it through the fronts. This ball really picks up in the middle of the lane and has a slow response time to friction. The backend motion is very even in an arcing motion. This ball is perfect for fresh conditions with medium volume and length. The ball motion allows me to play straighter angles and play closer to the friction without having the ball overreact. As the night went on and I had to continually chase the pattern left and open my angles a bit, that’s where this ball got out of its comfort zone and I started to leave weak corner pins. Luckily, Global 900 introduced the Ember to be the next ball out of my bag. The Cove will be a great ball for lower rev players who are looking for a very controllable but strong ball.

The 900 Global Cove is 900 Globals newest 800 series ball. The Cove features the Magna A.I. core wrapped in the RB 85 hybrid cover and finished at 4000. The Cove helps bridge the gap between the bigger symmetrical balls like the IDOL and balls like the !Q Tour and Ultimate Wrecker. The Cove is now available from any Storm VIP Pro Shop!

Orientation: Right Handed Rev Rate: 400 RPM Speed: 16-17 MPH PAP: 4 ½ over and 1 1/8 up Location: Enterprise Park Lanes, Springfield MO Pattern: High Volume THS VLS Layout: Layout 1: 4 5/8 x 4 x 2 ½ (Pin above bridge) Layout 2: 4 ¼ x 4 x 4 (pin below bridge) The new Cove surprised me. I was not expecting to like this ball, even though it looks great on the shelf. But I was very wrong. This ball is strong but not crazy strong and it revs up nicely and stays continuous. The hybrid cover makes sure it comes off the friction well and the continuous rev’ving motion really fits the eye. I’d be very comfortable throwing this ball on a lot of conditions. Fresh and for a good long time in the transition. I think eventually it would get a little slow but that’s when the Ember could come in. Don’t sleep on this Cove like I did, it’s a really good piece!

This ball is.just what my game was looking for. I've used it three times and it gets down the land with ease. The Cove is my favorite ball. I'm a senior bowler with average of 180 I think this will help improve my average by at least five. Pins

The Cove is a hybrid that was missing in the 900 Global brand. It’s very versatile for multiple lane conditions. My layout is 4 3/4 x 4 1/8 x 4. The layout is pin down, which allows me to keep my angles closer to the pocket, and allowes me to start on the fresh conditions. The Cove is very predictable, drives through the pins great, and fits the gap in the 900 Global catalog! Definitely a great ball to start off with!

The Cove is a great ball to start your night off with. I can really utilize the fresh with this ball from the start. Expect this ball to be a nice continuous motion in the backend and nothing to sharp off the back, very controllable. I find this working well around the fresh and into the transition phase. If you’re looking for something to throw on the fresh and can use during transition, this is one to have in the bag. Cove and Ember are ones to keep together in the bag, they work very well together.

900 Global Cove Ball specs: All new Magna A.I. core with a new aggressive RB85 hybrid coverstock with a factory finish of 4000 grit. My Specs: Rev rate 420’s, ball speed 15.3 to 15.8 mph off the hand, axis tilt of 16 degrees and axis rotation of 70 degrees, PAP is 3 15/16th up 3/16th. Tested on Pro-lane surface on a 43ft medium volume house pattern and 37ft sport pattern. The all-new 900 Global COVE is new from every aspect. Developed by the great minds at SPI, the COVE was engineered to add an aggressive hybrid to the already popular Global line up. Global’s signature single core density continues with the all new Magna A.I. core to deliver consistency down lane shot after shot from the fresh condition and through the breakdown. Geared towards the traditional house pattern lengths and volumes, the new RB 85 hybrid cover adds an aggressive cover above the other THS balls like the Rock Star and Equinox. For me, I drilled it 2 x 6 x 3, one of my favorite layouts I used for league play, and the ball performed well above my expectations after seeing the ball being used at Bowl Expo 2025. The consistency of the reaction was very impressive. Stronger reaction than my Rock Star and RST Hyperdrive Solid, but less angular than the Gremlin and Ember. The COVE won’t replace my Rock Star, but when the Rock Star is not quite enough strength in the backend, or when the Gremlin or Ember is too angular in the back end. A strong alternative benchmark ball over the Rock Star, iQ Tour series, or Phaze II. #SquadRG #3GShoes #ViseInserts #CoolWick #BowlersSupply #abcnorthlanesandlounge

I was very shocked of how much I liked this ball. I put my favorite layout on this which is 50x4x20. This ball is so smooth yet strong. It has become a favorite in my bag so far, especially on tough sport shots.

900 Global has done an outstanding job in creating and formulating the all-new Cove! The Cove is an excellent combination of benchmark and power! With the all-new Magna A.I. Core and the RB85 Hybrid Coverstock, the Cove will certainly bring results to any straighter player’s game. So, stop into your local Storm VIP Pro Shop today and have your 900 Global Cove ready for this season’s league, as the Cove is the mid-priced powerhouse that will save your wallet yet destroy the competition! The 900 Global Cove makes an excellent choice! Rick Klimowicz Storm Products Pro Shop Staff Roll the Ball Pro Shop Penndel, PA

The Cove has a motion that has been missing in my bag for a while. Smooth, controllable, and a tad early. Perfect ball for game 1 during league. Not to mention, the color scheme of this ball is amazing - reminds me of a sandy lagoon. Ball will get a lot of use from me! 5/5.

900 Global Cove Ball Review Layout-5x4x2 Surface-3000 Grit Abralon RG-2.49 Differential-.044 The Cove features the new Magna AI core wrapped around the RB 85 Hybrid coverstock. The Cove will create a smooth but continous backend. The Cove is a symmetric core with a hybrid coverstock. I feel like the Cove will be a great option on fresh oil when you need your ball to pick up but still control the fresh backends. The Cove won't be as strong as your bigger asymmetrical balls. So it will fall in the middle of your arsenal. The Cove and Ember were designed to compliment each other to give you a 1-2 punch. https://www.facebook.com/reel/744385005251195

The 900 Global Cove has quickly become one of my favorite benchmark pieces in the current lineup because of how smooth and reliable it is on medium to heavier conditions. Compared to the Zen 25, the Cove is noticeably more controlled and rounded off the spot, giving me a motion I can trust when I don’t want the extra pop or flare the Zen brings. Against the Origin EX, the Cove feels like a clear step down in overall strength, which makes it the perfect option once the stronger covers start reading too early or getting too jumpy. I really like how it pairs with the Ember as well—the Ember gives me that cleaner, more angular look, while the Cove blends everything out and keeps me in the pocket. For me, the Cove fills that ideal first-ball-out-of-the-bag role, reading the lane early enough to give control but still continuous enough to carry when the lanes transition.

900 Global released 2 new pieces this month. The Hybrid version is the Cove. I drilled my Cove 4 3/4 x 4 x 2 standard pin up drilling that I like to use for my symmetrical bowling balls. 1st impressions were very smooth reaction and very controllable. Reminds me of a ball down from the RG Rock Star. Great ball for the 1st game of league or on the fresh sport pattern. With my roll, I could use it for the 1st couple of games of league but when I had to chase it left it was having trouble getting the corners out. But Team Utah has a lot of choices to use when we get left. (Storm Ion Solid). Great shelf appeal and great medium ball to have in your arsenal.

Layout: 40 x 4 3/8 x 35 The Cove is a ball that every bowler should have in their bag – it is controllable, smooth, and has all the qualities of a great benchmark bowling ball. The Cove is right at home on medium to medium-heavy patterns, and has a smooth arc reaction. It doesn't have a ton of midlane, which if it did would push it more into the heavy oil ball category. Instead, it is clean enough to still be usable when the lanes break down. This ball is a perfect step down from the Sublime Focus or Phaze 2, both of which have quite a bit more midlane traction.

The Cove was one of the balls from the 900 Global dual release back in August along with the Ember. Both balls have the same all-new symmetric Magna A.I. Core. On the 15# ball, the RG 2.49 is in the middle (not high or low) and the Dif is 0.044 which is on the lower end of middle. The Cove features the all-new rapid oil absorption rate Reserve Blend 85 Hybrid Reactive cover. Based on 900 Global’s coverstock numbering system, that makes it stronger than the Zen 25 (RB 83) and weaker than the Origin Ex (RB 89). What does all this mean? The Cove sits squarely in the medium/middle range. It’s a middle of the bag symmetrical. I’d say it’s similar to Rockstar. It comes with 4000 factory finish, but appears to be versatile. If you want it to pick up a little earlier, sand it up a little. If you want it to be a little cleaner, let it lane shine or put some polish on it. Either way, the word that best describes it is smooth. I drilled mine with the pin under my middle finger which is 5” from my PAP. It feels like it’s better keeping your angles a little more square. If you want to open up a lot, you probably need something cleaner with more backend (Ember ?!?) or even more Dif. The color of the Cove can be polarizing. At first, I wasn’t wild about the bright lime green. But once I heard it referred to as the sherbet ice cream ball, it grew on me. Bottom line, if you are looking for a smooth middle of the bag symmetrical ball, you should consider punching up a Cove.

Introducing the 900 Global Cove with the all-new symmetric Magna A.I. Core and hybrid reactive coverstock. This ball is ideal for medium to heavy oil conditions when you need smooth and continuous ball motion. I am slightly speed dominant, rev challenged 220-250ish, low tilt and high rotation. I drilled mine 40 x 4.5 x 20. My axis point is 4 3/8 over 1 3/8 up. I love this ball for medium oil conditions. This ball is clean but reads the midlane well and gives me an even and continuous motion. This is the perfect house shot league ball that I can stay right with in the games 1 and 2 of league.

900 Global released a pair of complementary balls at the same time - the Cove and Ember. Both of the balls share the same Magna AI core, but The Cove is has the Reserve Blend 85 Hybrid cover finished at 4000 Grit. Personally, I found the 4000 grit a little bit too clean and initially scratched it up with a used 1500 pad and completely changed the reaction of the ball. In all likelihood, I’m going to keep it at 2000-3000 to put a bigger separation between the Cove and Ember. The rougher surface will get the Cove to read the lane a bit sooner and smooth it out some. All in all, the Cove and Ember will make a great 1-2 punch, starting with the Cove and moving to the Ember as the lanes break down. Layout: My Specs - Speed - 16 mph, Rev Rate - 280. PAP 5 3/4 x 1/2 Up

Cove does exactly what you expect it to do. Very predictable ball. Went with a 5x4x2 drill pattern layout as a two handed bowler and I know exactly where it's going to go every time. Quick shipping from bowler Mart too. Thank you!
