This is a new Storm Summit Ascent ball from High Sports. Please refer to the outer box in the photos for the specifications. The following is quoted from High Sports: The ASCENT, a global release, is the fourth generation of the Summit, which was the first to adopt A.I. technology. The high-density Centripetal HD weight block provides an early roll from the front to the mid-lane, giving the impression of a smooth, unwavering motion (less affected by oil) rather than biting into the lane, and even providing a sense of stopping at the breakpoint. Its consistent roll minimizes power loss, and the strong impact on the pins allows bowlers with low revolutions to experience messengers they have never seen before. This product also has very good ball balance and is highly versatile, making it easy for various types of bowlers to handle. The A.I. core technology, developed to overturn the common sense of the bowling world, provides a stronger pin action that knocks down pins even with balls with low revolutions or without an angle into the pocket. In addition, the adjustment range of the core power has been expanded, allowing for more detailed inertia values to be set for each ball weight. The Centripetal HD-A.I. core minimizes power loss with its consistent and strong roll.
