The Ebonite Game Breaker series is one of the most trusted lines in bowling and now provides more value and performance. Game Breakers continue to dominate the mid-performance category, and the new GB4 Hybrid might be the most exciting release in this line yet. Adding the HK22 base to a hybrid Game Breaker means versatility and strikes – lots of them. This exciting addition of a base coverstock that is changing the game to the already proven and famous Enhanced V2 core will make this one of the most anticipated Ebonite releases in quite some time.
