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.
The Ember is the ideal companion to the Cove, fitting just beneath the Zen 25 in the lineup. Like the Cove, it features the ALL NEW Magna A.I. Core, offering exceptional stability and control. What sets the Ember apart is its RB82 Pearl Cover—an aggressive, high-response shell designed to deliver increased backend motion with minimal loss of traction in the oil. With the balanced design of the Magna Core, the Ember provides a perfect blend of predictability and explosive finish downlane.
Here's what 900 Global has to say about the Ember:
The Ember will complement the Cove perfectly. Fitting just below the Zen 25, the Ember utilizes the same ALL NEW Magna A.I. Core as the Cove. The difference is the cover. RB82 is an aggressive pearl cover that was designed to give you more backend while sacrificing very little traction in the oil. The Magna A.I. Core helps keep the Ember on-line and will be sure to balance out predictability and backend performance.
