A drastic departure from our traditional symmetrical core or symmetrical weight block designs in this line, the asymmetrical Rondure™ Core was developed to increase overall ball motion throughout the lane without the aid of an added balance hole. Paired with our most recent formulation of eTrax™ solid coverstock technology, this ball has solidified the position as the “Benchmark Ball” for the Roto Grip line.
