A X-Blem bowling ball from SPI Bowling Products (Storm, Roto Grip, and 900 Global) will have an X stamped by the serial number. X-Blems are seconds due to a cosmetic blemish similar to an X-Comp, but the specifications fall out of the 2-4" & 2-4oz. range. The reaction of the bowling ball will be the same as the first-quality ball.
It's an IQ Tour like you've never seen before... Meet Storm's IQ Tour 78/U!
Storm's latest release to the IQ Tour line is new, different, and it's urethane. IQ TOur 78/U features a newly formulated Controll 78 Solid urethane coverstock, finished at 500-Grit Abralon. This PBA approved cover will offer smooth controllable predictability on the lanes.
Inside, the C3 Centripetal Control symmetric core has a low RG, which will help the ball maintain urethane-like reaction. You can expect smooth arcing motion on drier lane surfaces.
Here's what Storm has to say about IQ Tour 78/U:
If you’re looking for a smooth and predictable reaction, the !Q Tour 78/U may be for you! We’ve been testing new urethane materials and the combination on this bowling ball creates a new reaction different than current urethane options in the bowling industry. The new Controll 78 Urethane is also PBA® compliant.
