Used this on a heavy-medium tapered house shot, my oh my this thing made my hybrid look like plastic, i don't have the ball with me to tell you drilling and such but i'll have it in a review soon enough, a weight hole though may be needed the scale wasn't there (old one broke, new one on the way) so we shall see but its suprisingly strong, it reved up medium late on the lane and had a pretty big change of direction when it decided to move so i'm impressed
