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.
