This is a new Storm Identity ball from High Sports. Please refer to the outer box in the photos for the specifications. The following is quoted from High Sports: Developed in collaboration with Jason Belmonte and Storm. What Mr. Jason pursued was the ease of throwing and scoring ability with a smooth reaction. The "ID™ A.I. Core" has a medium RG value of 2.510, a high differential value of 0.055, and a low PSA value of 0.011. As a result of countless tests of core values, coverstock, and surface finish combinations, a ball that far exceeded expectations was completed. The medium RG value maintains power to the back end, providing a high strike angle of entry and excellent control. After testing numerous covers, the selected cover is "ReX Pearl Reactive" finished with Power Edge. It is smooth on the front end of the lane, but shows an incredibly aggressive back-end reaction. Even in rough conditions or if there is a misalignment with the board at the time of release, the strike rate is very high, and it is a ball that is easy to throw for single-hand stroker bowlers.
