Professional bowlers on tour, and those that want to bowl like them, like bowling balls that offer more hook and continuous down lane motion while driving through the pins. It is this type of bowler that the Roto Grip RST X-1 hybrid reactive bowling ball was designed for. This high-performance asymmetrical ball has a core that produces consistent core torque as well as energy transfer down lane. This RST (Roto Star Tour) core is wrapped with a versatile MicroTrax Hybrid coverstock which generates ideal responsiveness on both oil and friction.
