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.

Ebonite Enhanced V2 Core

The Enhanced V2 core has been a staple in the Game Breaker line for years. This low RG, medium differential combination produces easy revs throughout the entire lane. The flare potential this core offers is large enough to create a strong, yet predictable move to the pocket at the backend of the lane.
