Add a little zing to your game with the Radical Zing! Hybrid 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 a combination of Radical's proven Forged 2 Solid and Forged 2 Pearl coverstocks. This core and cover combination creates more length and more backend recovery than the original Zing!. 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.
