From the manufacturer

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'.
