I had a 2nd one drilled up 6 x 3 now it is good ball for oil, my first one was drilled 4 x 2 1/2 and hooked in my back swing. The 6 x 3 ball revs up hold until it sniffs dry and boom off it goes to the pocket. My speed is on the higher side probably 17 mph at the pins and rev rate is between 280-320 somewhere with almost no axis tilt and 60 degrees of rotation off my hand. If a cover on a bll is too strong most balls stand up and go left for me way too quickly. That is one reason you will see my dump brand new stuff so quick all the time, plus i am just plains nuts. My pin ended up over the left edge of the middle finger it looks like a left hand drilling if you dont pay attention to were the cg is placed.
