The Clone seemed to waste no energy until it got to the breakpoint and then made a very strong move toward the pocket.

Stroker saw the best reaction of all three bowlers on the fresh medium oil pattern with the Clone. His lower rev rate resulted in a more controllable move at the breakpoint compared to the other two bowlers. While his UFO Alert wanted to grab early if he was too straight up the dry on the outside part of the lane, the Clone didn’t have this problem. He was able to get the Clone to the breakpoint easily from more direct angles, turning over very sharply downlane.
