Radical No Doubt Hybrid Bowling Ball
We have developed a new cover formula, Advantage Plus Hybrid. The Advantage Plus Hybrid cover offers different performance characteristics than any of the HK22 base formulas. We found that the Advantage Plus cover was a little more responsive in the mid lane and slightly more controllable at the end of the pattern.
