To create this very special PRO-Motion, Jason teamed up Storm’s Research and Development department to create a weight block design that is unique and benefits bowlers of all styles. It is a dynamic symmetrical piece that has some very unique characteristics. For bowlers looking to roll their best scores, the PRO-Motion gives total performance from foul line to head pin with a ball motion akin to the pros'.
The PRO-MOTION™ features the new PISTON™ core and the performance proven SPEC™ solid coverstock. This combination of lower RG and Higher Differential weight block combined with an aggressive solid coverstock will deliver the ultimate in “BENCHMARK” performance.
