Add a little zing to your game with the Radical Zing! high performance bowling ball! The core designed for the Zing! was done with the Katana in mind but with more dynamics offering the driller more options. This ball is wrapped with Radical's proven Forged 2 coverstock. This combination creates Radical's desired ball motion of being very aggressive off the spot with a big backend reaction. The Zing! also utilizes Radical's DynamiCore technology that increases the balls coefficient of restitution which causes the pins to reflect off the ball faster resulting in a higher stike percentage.
