The Roto Grip RST X-3 uses the same asymmetrical Roto Star Tour core that was used in the RST X-1 and RST X-2. The X-3 uses the same MicroTrax Hybrid veneer that was used on the RST X-1, finished with the new 4K – Fast process that gives it a bit of a shinier look than the X-1’s 3000 grit box finish. This helps to give the RST X-3 more length than the X-1 and a smoother motion than the polished RST X-2. When all was said and done, the RST X-3 matched up best to our medium oil pattern for all three testers.

Cranker has matched up really well with the RST X-1 and RST X-2, so he had high hopes for the X-3. He saw the best motion out of the three bowlers on the medium oil pattern. With plenty of length through the front, he had a smoother reaction than both the X-1 and the X-2 on the fresh. With the box finish, he saw his ball tend go a bit more forward at the back end, allowing him to control the motion and still carry. As the cover started to glaze up with oil, his reaction got even better and he started to see a sharper move and more continuation downlane, which allowed him to open up his angles even more.
