I drilled my 916 with the pin over the ring finger, MB right of the thumb hole, and a low flare increasing hole. Pin is 4 inches from my PAP. My PAP is 4 1/2 over and 3/4 up. The pin was out 3 inches from the CG before drilling. The ball had 3.2 top weight before drilling. My ball speed is medium at best, my rev rate is also medium to high.
Out of the box, this ball is very strong and could be used as a heavy oil ball. It burned up a little quick on the house pattern that I bowl on, but got better with use and the shell soaked some oil and calmed down. The hitting power is incredible, I was able to get some messenger head pins that I don't usually get.
In order to get more use from this ball, I hit the surface on the spinner with a towel that had Storm #2 polish on it. This shined the surface, but left some texture and made the surface more tacky. SHAZAM!!! This ball has been absolutely awesome since making this adjustment. More skid on the dry, but still reads some in the oil. I shot 300 in league the first set with it, and my low set is 723 on my Monday night league. Carry power is still tremendous, but the lanes play tighter now, and the ball doesn't burn up at the break point, it is actually pretty sharp. A 4 inch pin to PAP is pretty strong for me, as I usually lean towards 4 1/2 to 5 1/2, but this layout is very nice for this ball.
I feel like high speed players will like this ball on fresh oil, as it should give them some good bump on the dry. Twisters should like this ball on some oil, but will probably like some polish on it to make it more versatile. Straight players should like this ball, but may need some shine depending on how much oil being bowled on.
I think Track has winner here for medium to heavy oil. This ball seems to be very versatile, and shell doesn't seem to be soaking any oil, and seems just as strong now as it was 45 games ago. (counting practice)
Thanks to Steve Szabina with Ebonite for recommending this ball to me. Have sold three so far, and have three very happy customers, worked perfect on the correct condition and with correct surface prep.
