Storm continues their Belmo Signature series of bowling balls with the Storm PRO-Motion. For this ball Storm and Jason Belmonte teamed up to create a ball with a unique weight block, the Piston core, that works with all styles of bowlers. This core is wrapped with the SPEC Solid Reactive coverstock which is not affected by heavy oil and keeps a powerful motion through the backend of the lane.
