X-Comps generally have a cosmetic blemish that in no way effects the reaction of the ball making it nearly as good as a 1st quality bowling ball. The Pin to CG Distance will be 2-4” and the Top Weight will be within 2-4 ounces. An X-Comp will have a C stamped by the serial number. The label on the box is stamped X-Comp and is marked with a small red number that denotes the specific issue.

The Perfect Scale®: Helping Bowlers Make Better Decisions. Because each manufacturer uses a different method for indicating a ball's hook potential, developed a way for the consumer to compare bowling balls across all manufacturers.
