Brunswick Mastermind Einstein Bowling Ball

“This ball being hybrid fits in nicely between my scholar and my intellect. Clean through the front with the traction in the midlane without reducing my backend motion, this one is a winner.

The new Relativity reactive coverstock is Brunswick’s latest innovation in our performance enhancing technology. This aggressive Hybrid coverstock produces easy length through the heads with outstanding traction on the backend to achieve ultimate flip.

The new Modified Mastermind Low RG core features a single density squared-off elliptical inner core. The core is dynamically designed to extend the rotational energy, boosting angular velocity to transfer energy to the pins for increased pin action and higher scores.

The new Mastermind Einstein with its 4000 grit Siaair Micro Pad finish, provides easy length through heads, mid lane traction with an exceptional move on the backend on medium to oily lane conditions. The Mastermind Einstein can be drilled using the standard drilling techniques developed for asymmetric core bowling balls. At Brunswick, the unique core shape of each individual ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range. At 12 and 13 pounds, Brunswick uses a generic core shape with a RG-differential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used.
