Roto Grip RST X-3: RST core with MicroTrax Hybrid cover stock with 4K fast /exceptionally light polish. The layout is 60 x 1 ½ x 65.
Currently using it on a 46ft THS that was a BIG cliff on the back of the pattern and not really blended well front to back and side to side. Super dry outside of 12 and super heavy conditioner between 16 to 16 across the boards.
Comparing it to the RST X-2, the movement is early in each part of the ball motion due to hybrid cover versus pearl cover, which is understandable and expected, BUT the main difference is that the X-3 still has a good bit of angle into the pocket, where the X-2 tends to be super over/under reaction because the pattern is not blended well. The X-1 had too much early movement and would lose most of its momentum because it would try to “dig in†too much in the front of the pattern and the heads. I changed the surface to 2000ab to see what the difference was and there really was not much difference in the movement, the ball does look better with the increased lane shine at 2000ab over weeks of using it. I call this core ASYS-LITE, because it is on he “lighter side†of ASYS cores out there and gives me a smoother reaction that other ASYS cores.
