The Rocket A.I. adds to the Storm Thunder line by giving customers the option of a pearl coverstock. Like the monsoon and typhoon, it is in the mid-performance range, but it has a different purpose. The A1S Pearl Reactive coverstock gives the ball a strong backend reaction on medium oil, unlike the Monsoon, which uses a solid cover to read the midlane. The Rocket A.I. moves down the lane before making a more precise move at the breakpoint. In the middle is the Booster Core, which is a symmetric shape that Storm's A.I. outer core technology makes even better. This new version of Rocket lowers the RG and raises the differential, making the ball better for today's lane conditions than older versions.
