An amazing piece from the Brunswick research guys. This ball has the predictability you need in todays game. I drilled this with 55x4.5x45. Rolled on 45' flat pattern. I wanted to really see what this ball would do on a flat, non-crowned condition. With a 17 off hand speed, matched tilt/rotation, 325 revrate, and a lefty to boot, this ball really makes the transition off the spot smooth and strong. There is no need to have someone help break down the pattern for you. The core design along with the cover, allows this piece to read the mids really well and have the energy to make the turn with ease. If you need a ball that reacts well on the heavy oil patterns, you are cutting yourself short if you don't give yourself the chance to try this intelligent piece. Mastermind original was really a great piece along with the Scholar. But this ball deserves the name Einstein. It's the smartest decision you could make. Nuff said. Get ya sum!!!!!
