it is sad to say but I have almost no clue in how bowling balls are drilled...meaning i don't know where things should be, CG, Pin, PAP, etc., to do certain things with the ball....i am not a newbee bowler...average around 220, but want to take my game to the next level and would like to learn a little more about drilling so i am not given the runaround by pro shop guys thinking i dont know what i am doing....can anybody point me in the right drection into the education of drilling, web sites and such or give me some basics to start with???
