An X-Comp will have an X stamped by the serial number. X-Comps generally have a cosmetic blemish. The Pin distance is in the 2-4” only range and top weight is 2-4 ounce range. The reaction of the ball will be the same as a 1st hand quality ball. The package is marked with a small red number that denotes the specific issue.
An X-Blem 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 / 2-4 range. There are a couple of areas that the ball would not meet some first quality manufacturing specifications (i.e. core chip or a mis-used core). The reaction of the ball will be the same as a 1st hand quality ball. The package is marked with a small red number that denotes the specific issue.
A Pro-CG is where the CG ends up extremely far left or right of the Pin and MB. If you draw a line from the Pin through the MB and then draw a perpendicular line at the half way point of that line. Go out 2 1/2” and then connect the points to create a diamond shape. If the CG is outside that diamond then it is a PRO-CG. This is a first quality ball and lends itself to several special drill options. Please see the enclosed drilling instructions.
A Pro-Pin is where the Pin distance from the CG is 5 ½" – 6 ½” out. Anything more than 6 ½” would be termed an X-Blem. This is a first quality ball and lends itself to several drill options. Please see the enclosed drilling instructions.
Heavy (H): 12-15 ounces
Medium (M): 8-11 ounces
