A X-Comp bowling ball from SPI Bowling Products (Storm, Roto Grip, and 900 Global) will have an X stamped by the serial number. X-Comps generally have a cosmetic blemish. The Pin (Core Top) distance is in the 2-4" only range and Top Weight 2-4oz. range. The reaction of the bowling ball will be the same as the first-quality ball.
Use darkness to see the light on the driest conditions with the Storm Pitch Black Bowling Ball!
The Pitch Black is designed to combat the dry lanes and short oil patterns that are often found today. On these conditions, you want a predictable ball motion that is easy to control and reads all parts of the lane.
For this type of reaction Storm paired a new solid urethane formula and ended up with the Controll Solid Urethane coverstock. Mid-lane roll with control!
The new Capacitor core is designed to regulate your flare potential which makes the ball more controllable and won't overreact on short oil. High rev players and slow ball speeds will love the Pitch Black!
