The Collision was many players’ go-to ball when they needed an asymmetric ball that moved on the backend. The Brutal Collision is a fantastic follow-up and uses an even stronger reacting base cover, HK22. Adding HK22 to the Collision core and a polished, solid cover creates even more hook and a devastating backend reaction. As promised, HK22 will create more color clarity, and the Brutal Collision is bold and vibrant.
