No need for smoke and mirrors here! Roto's new Mystic bowling ball fuses together the single density symmetrical Helios core, with an extremely adaptable Ultimate Grip pearl particle coverstock. The ultra low RG core with medium to high differential has been a rising star in the Roto Grip product line. These value priced balls have become the new benchmark equipment from Roto Grip. The Ultimate Grip features a 2% polished pearl particle coverstock. The particle gives this ball the traction it needs coming off the oil pattern to give you strong, but yet controllable backend reaction. The delivery will shock, and mystify all!
