Step the surface up 500/1000/2000/4000/worn 4000 pad. When you get close to the reaction you are looking for, you can use polish to fine tune.
My experience is that most polishes give you more length, and that some polishes increase the reaction off the dry.
We have several bowlers killing our house shit with the Mastermind. My brother used his all three games Sundah night and shot 670 with a 180 in the first game. He shot 269 the third game and we have 5 men teams.
My Mastermind Intellect set up the same as my Mastermind is covering more boards although it is cleaner through the front. May be because it is new.
Ultimately, it depends on the way the shot plays and breaks down, the way you are trying to play the lanes and on how you throw the ball. The Mastermind is more versatile than many would think. It does a great job of blending over under and will carry when they get dry if you play the correct angle.
