The Breakaway has an RG of 2.528 and a differential of 0.041. This combination of core dynamics and HK22 Solid, which is polished, yields a very definitive backed reaction. Our goal was to create a symmetrical ball with a massive backend motion while increasing the hook window to be sure it has plenty of continuation. The Breakaway hits the Radical target of increasing backend motion and maintaining continuation through the pins. Combining the Breakaway symmetrical core with the HK22 polished solid cover, you get great performance and a great shelf appeal.
