Hammer Purple Pearl Urethane 78D

Hammer Purple Pearl Urethane 78D The Hammer Purple Pearl Urethane 78D brings the legendary reaction of one of bowling’s most iconic urethane balls into a new, competition-ready design. Built around the all-new Super LED core, this version dramatically increases differential and flare potential while maintaining Hammer’s proven thick-shell technology. The harder 78D urethane formulation provides the smooth, predictable motion urethane is known for, while the updated core creates more overall motion and versatility than traditional urethane options. The result is a controlled shape that reads the lane with confidence while still delivering strong continuation. For bowlers who love the classic Purple Pearl look and motion but need a version that fits within modern rules, the Purple Pearl Urethane 78D delivers the familiar control and reliability Hammer urethane is known for.

Hammer Purple 78D

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.
