The Roto Grip Assault is a work of art in bowling ball innovation. The all-new asymmetrical Concave Radius High Torque weight block is the most versatile weight block ever. Concaving one side of the weight block acts as
a dynamic counterbalance providing constant motion for strong Hook-&-Roll characteristics. Encasing the weight block is an improved Sure Grip Traction Plus(tm) cover with increased particle loading maintaining traction in the
heaviest of oil. The Traction Plus cover is easily adjusted with use of pads, sand paper and polishes.
