Combining great features from different successful bowling balls to create even better new balls is exactly how Pure Envy was created. A lot of development goes into creating the next great Hammer ball, and with Hammer’s extensive catalog of successful cores and covers, the process is extensive but exciting. The goal with Pure Envy was to complement the performance of the Extreme Envy in oil and provide backend motion in a dull ball that reminds Hammer fans of the Effect. To accomplish this goal, Hammer started with multiple core designs, and the clear winner from our testing was the original Launcher core. The Launcher core numbers are strong; the high differential and asymmetry help create the big overall motion. The cover options with Hammer’s additive packages are vast, but the new Cohesion additive combined with HK22 that was first seen in the Effect creates an unmatched ability for backend traction, and this, along with surface, gives Hammer fans a new big ball for oil. You will not want to hit the lanes without Pure Envy in your bag this bowling season.
