Hammer Purple Pearl Urethane 78D Review
The PPU 78D upgrades the legendary Purple Pearl Urethane with more length and a smoother arc. The go-to when reactive is too much. $149.95.
All right. So, it's Purple Slammer 3.0, 4.0, whatever. 0 after different iterations and different colors and different whatever else. But we are going to do things a little differently here because I've been editing videos for a month and a half solid and I'm kind of tired of it. So, um, and this is a different kind of a thing anyway. Throwing urethane. We're not going to go we're not going to do the typical ball review thing. So, uh, I'm just going to get out there. We're going to throw it. We're going to talk about it. And, uh, the big deal
with this one is, of course, it's So, the Black Hammer cover is a harder version of the original purple cover, but it's got the same core. Now, this one has the same cover as the Black Hammer, which is the harder version of the original purple, but this has a stronger core in it to kind of help amp it up a little bit. And I did go on ahead and put a 4-in pin on this because this core has enough differential to flare. And so, we want to see what the
difference is. Um, normally I drill 4in pins on urethane anyway. So, I was going to do that on this just to really see what the difference is. And again, haven't thrown it yet. This is typical urethane. So, I'm going to line up in like the 10 to 5 zone and watch it go Brooklyn. So, I'm going to stand on 16 to start. And we're going to try to watch it hook off the planet here to begin with because that's what
that's what urethane does. So, this one I'm not sure we're going to be able to bend just because of the harder cover, but it does flare. So, you know, that's what the real wrench in here is. So, what I've seen from them so far is that they do pick up hard early like
urethane normally does, but then it kind of is a little straighter down lane. It's not quite the the black takes time if you give it time. It's just kind of that clean, rounder, more continuous, gradual kind of momentum building kind of deal. This one seems like it's similarish, but it seems like it reads it seems like it reads the lane pretty quick and then just kind of walks or kind of almost fades after that.
So yeah, that's kind of what I'm talking about right there where you can see it grab and pick up, but then it just kind of is really soft down lane. So, I don't think it's going to be the like purple replacement because the black wasn't the the black wasn't the purple replacement that I don't I don't want to say that people were hoping that the black has ended up being really good. Of the 78 hardness urethanes, I think it's it's still the
the purple was the best regular urethane ball. And in the 78 hardness realm, I think the general consensus is that the the black is is the best the best one of those. It doesn't do what the purple does. So, it still rolls pretty good for me. I'm kind of liking this so far. It does definitely read the lane harder than the
black does. And that's the big thing about flare is that people I don't think quite under quite understand it or pay pay enough attention to it that flare is such a big factor in in how a ball reads the lane because if the ball doesn't flare, it just rolls over the same oil tracks all the way down the lane. And so it's just it's hard for the ball to dig and get traction when it's rolling over the same oil over and over and over and over again. But when the
ball flares and every rotation, a new line and a new line and so there's fresh cover hitting the lane every single rotation on a ball that flares. And it it just such a significant difference in the way the bowling balls react flaring versus non-flaring. And that was awful timing. And I think I broke something.
I can definitely tell it feels feels different than the obviously it's going to feel different than the original purple. I really don't think I'm going to be able to move. I might be able to. This could be interesting. Definitely stronger than the black, which that was to be expected. Yeah, it's still one that still one that you're going to keep in front of you. It almost kind of feels in between. Yeah.
Um it kind of feels in between the purple and the black. It definitely has that kind of arcier shape like the purple where the black is a really round round uh continuous momentum building. And this kind of does the same thing, but it's got that it's more of a the original purple arc. It's got that that kind of arc to it.
Okay. Okay. So, there's the there's the 78 hardness thing showing up where I slowed that one down a little bit and it just didn't quite pick up. I gave it a little bit more room. Tried to bend it just a little bit. And it is, if you can see that all the way up there, it is flaring a little bit. Again, it's a 4 inch 4 inch pin, but it's not like 4 inch pinning an alert or
something that's got basically the same differential. This one has a whole lot higher RG. So, I can I can go stronger on the pin to get it to be stronger without being so so so early as well. So yeah, and this is going to be the trick of finding that kind of balance in the reaction where and like I said,
chromium is is there's oil outside on chromium, but for some reason the five board hooks. I get it outside of that. I've talked about this before in other reviews, but if I hit if I hit five, it hooks. If I get it to four, it skids. If I get it to six, it skips. If I get it to five, it picks up hard instantly for whatever reason.
Just like that. Like I hit six on that one and that just kind of kind of pushed right through it. That one I did slow roll a little bit and that was it picked up nice and and kind of kind of continued. But it is a different The black feels like the same thing all the way down the lane. It just rolls and rolls and rolls and picks up and picks up and kind of this one, you can see where it sees the lane and it sees it a lot harder when it sees it, but then it just kind of it kind of lays off, which is
once you figure it out, I think it's going to be nice to have, but it doesn't quite again, it's not going to do that the original purple thing. And that was that's going to be a flat 10. Or I just sailed it way too much on that one. This one is a You're not going to be able to bend this one
like the original purple, I don't think. Let me try one shot. I'm not going to move too much. I'll just going to stand on 19 instead of 16. I have no idea where it's going to hit at the arrows. And I gave that one way more room than I was intending to. Uh, but the original Purple, if you gave it some room and gave it enough time, it
would pick up and wind up and get back through it. And I think that's why it was such a problem. or where they thought it was such a problem is because you could get it to do the urethane thing from straighter, but then you could the the big thing about the 78 hardness stuff is you can't really get that far in with it. I mean, the big rev rates can get in a little bit, but it just doesn't get through the pins the right way. And the purple hammer, you could play third, fourth arrow with it. See,
fifth arrow, and it would pick up and get through the pins the right way from everywhere. And so that's where going 78 hardness kind of limits that to if you have it from straight or cool. And if you don't, you got to use something else. The purple, you could do whatever with it from wherever. That was better. That's what I'm talking about. That That was a good shot. That was pretty well
exactly what I wanted to do. And you can see it pick up and then just kind of fade. And that's the That's the 78 hardness thing. So, this isn't going to be. And I don't think anybody should have expected See again the the flare. If you can see it from there, I think you can. >> I don't think anybody really expected this. to be the purple, the original purple. And again, it dealing with
urethane that flares is always kind of weird, but I'm going to go ahead and move back and we'll we'll see if I can get lined up with it and throw a few shots now that I've been kind of limit testing a little bit. Okay. So, it still does kind of feel like urethane. So, even though it flares, it doesn't absorb. And so, even when I wipe it off, you
know, you'll still see that kind of glaze that gets onto urethane balls. Even when you wipe them off because the you're kind of in effect smearing the oil around a little bit. And even when you wipe a ball off, you're not going to get all the oil off of it. So that's where a ball that absorbs pulls that little bit of oil that's left on the cover because you can see it still this is very dull. Like if I if I would clean this or something, it
looks shinier than it is. It's still very dull, but it looks shinier than it is just cuz it still has a little bit of oil kind of sitting on there. I've gotten most of it off. But so that's where even though it flares, there's still oil that you can feel on the cover. I might even have to square up a little bit more than this.
Or just throw it slower. That was almost really interesting. So yeah, this feels like a black that reads the fronts and the mids harder and then almost lays off a little bit more, as weird as that sounds. So I think since the black doesn't doesn't read the lane so hard, it reads it more gradually.
This one's not exactly like giving up. There's my five board. So, yeah, if I find if if you have the friction for it, but the black does kind of that. It doesn't do it that much. It's not that strong or that, you know, the black needs a little bit more time than that. Um, but this feels to me like just a beefier version of the black
than it does like the original purple. So, there's the I would probably still Me personally, I would favor the black over this one
because I feel like I can control a little bit more of what it it it kind of does the same thing all the way down the lane. This one seems like it's almost kind of doing two things.
Now, the other thing here is that sometimes the black just isn't strong enough early enough. There's sometimes where it's just like even when you put a pile of surface on it, it's just not enough. And this this I think is going to be the ball that you can use before the black hammer when you need just the the ball to see the lane stronger earlier cuz sometimes the
black, like I said, the black just isn't quite enough. And that one I'm asking a little bit too much of it cuz I am still bellying it. Like I'm still giving it some room. This is this is kind of how I like the black one the best too. Just not necessarily going not like I ever go straight down and in. But I kind of like the black the
best when you can give it just that just walk it out those couple boards and let it kind of give it time to to pull back up. That's how I think it shapes the best into the pocket because again the harder covers you need to give them time to you need to give it time to kind of pick up and start going. It's not going to pick up so much so fast on its own. So that's why I think that if you're a little too direct with it, you have to
be kind of firm to get it down the lane, but then it doesn't have enough time to really wind up so it can be flat. Unless you're just giving it like the frozen rope. See, cuz if we kind of That was kind of going straighter up. If I kind of keep it in front of me, the combination of the surface and the flare is going to make it pick up do a whole lot more a whole lot earlier
cuz the black's going to pick up early, but then because it doesn't flare, it's just going to keep rolling. So, it's going to pick up early and then it's going to start walking earlier, if that makes sense. It's going to start slowing down as far as getting traction earlier than because this one's going to keep getting traction as it continues to flare. It's just traction, traction, traction. The black hits the lane and gets traction for for a couple rolls
rotations, but by the time the black hits the arrows, it's already sailing. This one continues to dig and dig and dig and dig. Let me try to keep a little bit more in front of me now. Here, this one's still going to be kind of dangerous. I would I would say when both of them could be in play, I
think people are probably still going to favor the black. But when the black is close and it's just not quite seeing it enough, this is going to be this is going to be something that I think people are really going to enjoy if I can out of the way of the camera. But I think you are going to get, of
course, you're going to have that with the black, too, but you are going to have kind of some of that with this ball because it's so much so early. Just throw couple more shots. Continue. I just adjusting my drift here.
See, cuz if I keep it more in front of me, it really wants to pick up fast. So, I feel like I have to give it away a little bit to keep it on line or to kind of get it down the lane a little bit to keep it on the line I want to throw it on. So, if you are going to play straighter with it, you need to be firmer with it. You need to give more speed. I'm just not sure if it's going to pick up right into the pins
or now that one I still was. I need to kind of adjust my angle. I might actually have to move right a little bit. I don't think that the drifting a little bit is going to be a thing. But that's the other thing is if I put more speed behind it, it doesn't give it enough time to to get the momentum going to kind of shape. Right. I'm going to move to 14.
Okay. So, I think it's it is you can play with the angles a little bit. So, that one I kind of I didn't grab it quite so much. But, I mean, I can do this with the black, too. So, this is one of those things where I can I can keep the black in front of you and kind of walk it down and in. This one again just sees the lane a little harder a little earlier.
So, yeah, the I don't have a black right-handed, but I think we've seen by now we've seen enough regular purples, original purples, and enough Blackhammers to understand what we're dealing with. I don't think I need to show them side by side, or I shouldn't have to show them side by side for people to kind of get the idea. Um, from what I'm doing these last
couple shots, just putting it down and in, it looks like a black that just picks up harder, a little harder. Uh, 14. And see that that one though doesn't really the black seems like it kind of builds a little momentum where this one seems like it does what it wants to do early and then it kind of lays off.
So I think you're going to have a little bit of a trade-off. The black I think is a little more balanced in the overall reaction. And see again that one I roll a little bit more and it gets offline quick. So there's going to be there are some definite differences between this one and the black. There's a lot of similarities obviously, but there's a lot of differences too.
And so I think obviously if you're a if you bowl tournaments where 78 78 hardness urethane is going to be a thing, just buy this one. I mean, it's just even if you already have a shadow tank or a a black hammer or I hope you don't have an IQ78. I wouldn't wish that on anyone, but
If 78 hardness urethane is a concern for you, you just got to buy it. I mean, and you can I don't you can say whatever you want to about ball reviewers, but and I don't I don't get any commission. I don't I got the ball, which is cool. I don't get any commission for saying it, but I think it's just obvious that if if you need 78 hardness urethane, if you're in in situations where you need it somewhere, I just can't imagine
not drilling one of these. So, I mean, it just is what it is. It's not an original purple hammer. It doesn't replace an original purple hammer. Uh, but it is more than the black. So, I think we are done with this one. I like it. I would definitely run these in I mean I would have loved love this one left-handed to run in tandem with my black both of them. Um but yeah, I I think it's good. It's not I'm not sure
what anybody was hoping for, what anybody was expecting. There are some cons, but I think we kind of talked through all that. So, this is this is going to be the review. I'm not sure I'm going to put anything I'll use the lower camera for some stuff and I'm not sure I'm going to put anything like together for it. But yeah, me likey.

Performance Analysis
Performance Analysis
Independent testing on a house pattern (Wall Street) at 500-grit surface conditions revealed that the Hammer Purple Pearl Urethane delivers smooth, controlled motion characteristics typical of modern urethane coverstocks. Testers observed that the ball produces a continuous arc with moderate hook shapeโmore pronounced than some competitive urethane options but manageable on fresh oil conditions. The key performance distinction emerged when comparing bowlers of different rev rates on the same pattern. Higher rev rate players (450+ RPM) demonstrated better entry angle and pin carry with this ball, while lower rev rate players (350 RPM range) found the ball somewhat earlier in transition, occasionally struggling to generate sufficient entry angle on direct pocket hits.
What emerged as particularly noteworthy was the ballโs behavior over time. After multiple shots without wiping, the Hammer absorbed minimal oil compared to some alternative urethane designs, remaining relatively consistent through a session. However, testers noted that this characteristicโwhile advantageous for durability and predictabilityโalso meant the ball didnโt develop additional traction as lanes transitioned. For bowlers able to generate adequate rev rate and axis rotation, the Purple Pearl Urethane tracked predictably and recovered well from light pocket contact. For lower rev rate players, different urethane formulations in the same price range may offer more aggressive motion and better carry potential on house shots.
Who Is This Ball For?
This ball is ideal for bowlers throwing 400+ RPM with moderate to high axis rotation who want a durable, low-maintenance workhorse for house shot conditions. The Hammer Purple Pearl Urethane excels as a reliable spare ball or dry lane specialist, particularly for players who value simplicity and consistency over aggressive angular motion. Its smooth, predictable shape makes it forgiving on slightly mis-hit shots, and the urethane coverstockโs resistance to oil absorption ensures minimal maintenance during league play.
However, bowlers in the 300โ375 RPM range should demo this ball carefully before purchasing. Testing showed that lower rev rate players may find the motion earlier and less angular than needed for optimal carry on house patterns. For this player demographic, exploring alternative urethane designs with more aggressive reaction profilesโeven within the same price pointโcould yield better results. At $149.95, it represents solid value for the right player, but fit and rev rate compatibility are critical to maximizing its potential.
The Pros

The ball is great gives just as much if not more miss room than the purple pin did, granted its not comparable to the green pin. but its great, hooks more than the og purple and thats exactly what i needed to create a stronger entry angle
My first urethane ball in well over 20 years. Grew up throwing urethane on wood lanes in the 80's and early 90's. Got this as what I thought would just be another tool in my bag. Just got it today, so limited time with it, but I absolutely loved it! My go to, benchmark, ball is a Hammer Cherry Vibe I bought in 2010. This Purple Hammer moves about as many boards, but has that classic urethane smooth arc shape with a strong drive through the pocket. Thick shell makes a difference. Heavy hitter. Reads the friction, but doesn't jump off it like my Vibe, or even my Rhino Pearl does. This might be taking the #1 spot in my bag that my Vibe has owned for 16 years.
Here's my take on the new Hammer Purple Hammer 78D. The new Purple has a Super LED symmetric core (modified LED core found in the original Purple to increase track flare) wrapped by a purple pearl 78D urethane cover. Box finish is 500 Siaair. For comparison purposes, I drilled a 78D with the same layout as one of my original Purples, 40 x 3 3/4 x 10. I also put a fresh 500 Siaair on the original Purple. I tried it on mostly fresh THS. From what I see, notwithstanding the increased track flare, there is a difference in motion. I had to be a little further right and on top of the dry to get the 78D to shape properly. A careful eye can see that the 78D picks up a little differently than an original Purple. It also seems like the 78D is a bit more forward off the spot so I used a slight hand position adjustment to get the ball to shape properly. In the end, the Purple 78D will be a useful tool in the bag. As I found it easier to "curve" an original Purple (to be expected given the different cover), I believe that straighter more direct angles through the front will help the 78D to be at its best. This new 78D Purple will be at its best on fresh patterns where a slow response ball to get control of the pattern is required. The Purple Hammer 78D is readily available. See your local pro shop for more information.
