            PERFORMANCE is the key to success and Roto Grip delivers once again with the release of the RS-Ptm. This MID-price STAR delivers the performance that most high price bowling balls can''t compete with.
We have taken the unbeatable Rotary IIItm core and surrounded it with an aggressive pearl particle coverstock. The combination of enhanced traction along with power of a low RG/high differential core will provide relentless reaction from foul line to the pit.
As always, we have given you a versatile product that can be drilled for a variety of players. The surface can also be easily adjusted with the use of Scotch-Brite pads or polishes.
So what are you waiting for? Get your STAR today!
Keep on building your own private galaxy!
