Roto Grip Exotic Gem Bowling Ball is uniquely special with it's Micro Trax Pearl coverstock. The crucial factor in this special Gem is that the ball can conquer through the Medium/Heavy Oil Conditions of the lane. The bowling ball would skid through the front end of the lane and dig into the midlane with it's Defiant LRG core. Roto Grip Exotic Gem is a high end Asymmetric pearl ball on the market today!
