Performance Analysis
Performance Analysis
The Hammer 78D combines the proven Hammer Super LED symmetrical core with the Urethane Pearl 78D coverstock to create a ball designed for control and precision on dry to medium oil conditions. With an RG of 2.63 and differential of .034, this ball provides a smooth, predictable motion that reads the lane early and maintains energy through the pins. The 500-grit factory finish gives it enough surface to grip the lane while still allowing for length through the front part of the lane.
What sets the 78D apart in the urethane category is its balance of control and performance. The symmetrical core design ensures consistent roll characteristics, while the urethane pearl coverstock provides the characteristic smooth, arcing motion that urethane balls are known for. This combination makes it particularly effective for bowlers looking to control the pocket or create better entry angles when reactive resin balls are reading too early. At $149.95, it represents excellent value in the urethane market, offering performance characteristics typically found in higher-priced options while remaining accessible to a broader range of bowlers.

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.
