The new “Brick Mirror Plane Asymmetric (MPA)” core design is completely asymmetric in shape, a highly unusual feature of the ball. The core is not high mass bias; however the low Radius of Gyration (RG) is not in the geometric center of the ball.
“This core shape was designed for a specific purpose,” explained Ron Hickland, Ball Design Engineering Manager. “The pro shop operator can tweak ball motion by making smaller layout changes when drilling the Brick. Those smaller layout changes will produce bigger performance changes in ball motion for the bowler.”
When you have a core as special as the Brick MPA, you have to make sure you have a coverstock that makes the most of the core’s performance. The Black/Blue/Red “GTR Hybrid” cover does the trick (finished 500/500/1000/2000 Abralon® Sanded). Look for the Hammer Brick just before Christmas on December 20th.
