Roto Grip Winner Solid Bowling Ball

Roto Grip continues their winning streak with the Winner Solid bowling ball. This ball uses the Altered Hotshot core wich was designed to offer the length and reaction needed at the HP2 performance level. The VTC-S18 Solid coverstock provides traction down the lane without reacting too early. This ball is best used on medium to medium/heavy oil conditions when itwill clear the front part of the lane easily and then give ample backend motion.
