Roto Grip’s RST X-2 uses the same asymmetrical Roto Star Tour core design as the RST X-1. The X-2 uses the new eTrax PLUS Pearl coverstock, which we found to be a game-changer in the skid/flip category. This cover digs into the oil even more than the eTrax Hybrid cover on the UFO Alert, while also providing a bigger move at the breakpoint. The RST X-2 performed extremely well on our medium oil test pattern and, despite having a polished pearl cover, it also provided plenty of hook with the box finish on our heavy oil pattern. This ball allowed all three of our testers to play to their strengths, as it struck with ease from just about everywhere on the lane.
