A Pro CG bowling ball from SPI Bowling Products (Storm, Roto Grip, and 900 Global) is where the CG (Center of Gravity) ends up extremely far left or right of the Pin (Core Top) and the PSA (Preferred Spin Axis or Mass Bias) marking.
This is a premium, first-quality ball crafted to the same exacting standards as the rest of these elite lines - ensuring top-tier performance and durability without any compromises.
Due to changes in the USBC rules for static balances and weight holes, Pro Pins/Pro Cg's no longer have specialized and unique layouts. These balls can be drilled using any of the SPI drilling layouts. NOTE - On Pro CG balls, the final placement of the CG (Center of Gravity) will appear to be in an odd location but this will not affect the ball reaction.
