## Description

The most successful 800 Series bowling ball just got an upgrade! The Zen Master features the S77 Response Solid Cover which has been purposely engineered for medium-heavy oil. Combined with the massive Meditate Symmetric Core…the Zen Master will be the strongest symmetric option 900 Global currently offers.MEDITATE SYMMETRIC CORE: As mentioned above, the Meditate Core will provide the engine for the Zen Master. Expect to see a ball that revs up quickly and keeps going throughout the lane. Since the Meditate Core is so large, pin up or pin down layouts will not alter the RG/Diff values very much at all post drilling. House conditions and sport patterns alike will be no match for the Zen Master.S77 Response Coverstock: The S77 Response Cover, in its pearl form, has more than proven itself. The Zen, while a dynamic and amazing piece, is still a polished pearl. When running into heavier volume patterns, nothing beats a dull solid. We have successfully optimized the cover into a version that will dominate medium-heavier oil patterns. The Zen Master will complement the asymmetric Reality perfectly to give the player a different shape on oily conditions.
