Roto-Grip Pro Pin Technology
PRO-PIN: A Pro-Pin is where the Pin distance from the CG is 5 - 6 ½†out. Although still categorized as a first quality ball it has limited drill options (see our Pro-Pin Drilling Options) that requires a certain type of bowler. Please consult your pro shop professional before purchasing one of these balls. Anything more than 6 ½†would be termed an X-Blem (second).
