The Brunswick Mesmerize high-performance bowling ball was designed to be the biggest hooking yet while still being effective and usable. It features a unique four-color appearance, a sharp two-color logo, and introduces the Tri-Elliptic core with DynamiCore2, and HK22 with Cohesion and Evo Solid additives. The Tri-Elliptic core has a D.O.T. design that anticipates drilling holes for optimal performance, resulting in a medium RG of 2.51, a high Differential of 0.056, and an Intermediate Differential of 0.017. DynamiCore2, previously seen only in the Quantum series, adds hitting power and durability. The Cohesion additive, combined with Evo series additives, creates the HK22C-Evo Solid cover, which is the strongest and can handle any volume of oil.
