- UpRoar

First Impressions
With the UpRoar, Roto Grip brings a fascinating new development to the market that stands out above all for its length and late reaction. Inside sits the Late Roll 51 core, which with a 2.55 RG and a 0.030 differential ensures a very clean motion through the front part of the lane. The 51AL Pearl Reactive cover is specifically tuned to store the ball's energy efficiently. The 1500-grit polished finish supports this trait by letting the ball glide effortlessly through the heads without building friction too early. Visually the ball is a real eye-catcher, and the makeup immediately conveys that this model was designed for later hooking motion. The technical match between core and coverstock has been achieved very harmoniously here.
Comparison
Comparing the UpRoar to the Hy-Road Pearl, the differences in backend reaction are immediately apparent. The Storm Hy-Road Pearl tends to read a bit earlier, while the UpRoar holds its energy a fraction longer and then responds noticeably more aggressively to the dry area. That trait makes it the perfect complement when the Hy-Road Pearl starts losing energy in the pocket. Although both balls have a similar orientation, the UpRoar offers a noticeably more dynamic change of direction. It is the ideal solution for situations in which the Hy-Road Pearl enters the pins too flat, since it generates the entry angle needed to move the pins off the deck reliably and efficiently.
On the Lanes
This ball shows its greatest strength once the lane has been played on a bit and the transition has set in. It needs a certain amount of friction in the backend to develop its characteristic hook, which produces maximum carry. When the boards in the front part of the lane dry up, the ball lets you move further inside and attack the pocket from a deeper angle. It works excellently on medium to dry conditions and is an excellent choice if you're looking for a clean, quick reaction. Thanks to its forgiving nature on slight misses out, it should keep your scores stable even in the later stages of a tournament.
