The Mastermind Strategy falls into the upper-mid performance price point in Brunswick’s line, just below the Nirvanas. It combines the Modified Mastermind Asymmetric core design with the Relativity Solid coverstock. This core has a higher RG of 2.504″ and lower differential of 0.048″ than the Mastermind Ultra Low RG core design from the early Mastermind releases, but it is the same as the core used in the more recent Mastermind Einstein. The coverstock is the first reactive solid used in this line since the Mastermind Intellect from 2014. The Strategy comes out of the box at a sanded 500/2000 SiaAir finish, allowing for a large amount of traction on heavier volumes of oil.
