Product details:

Officially, this is Storm’s strongest symmetric ball to date. Starting on the inside, the Centripetal HD weight block is surrounded by the ALL-NEW A.I. (Amplified Inertia) outer core. This new combination drives the RG down and the differential up ensuring this ball spins up fast and a lot! Paired with the TX-23 Hybrid Cover, the Summit profides enhanced oil absorption for even better grip on those slick conditions. Once you get one in your hands it’ll be tough to get it out.

• This upper-mid performance bowling ball introduces the bowling world to the TX-23 Hybrid Reactive coverstock and the Centripetal HD-A.I. weight block.
• The TX-23 Hybrid Reactive coverstock is a modified version of the successful TX-16 coverstock to give more grip on slick oil conditions.
• The core is the proven Centripetal HD that has been paired with A.I. (Amplified Inertia) outer core.
• The result is a lower RG and a higher differential making this Storm's strongest symmetric bowling ball so far.
