2.25 TW. O pin. Pin on PAP. (9" hole to bring back to legal). Ball used on 12-12 wall. 6 units from 8 to gutter. Great entry level resin or a diamond in the rough for the "big hand" folks. With core laid down, get a nice smooth move to pocket. Great hit. Not weak, but not a boomer either. Cover seems to be a sort of medium. Core not strong enough to jerk. In the right hands, would be a great dry lane ball.
