Well I am gonna get the No Mercy and would like the ball to keep its revs through the oil then come across. It will be my Heavy oil ball.

I added some pics of the drilling it currently has and some videos with my release with a orange sticker near the PAP. The ball is a 15lb Strike zone and the ball when down lane runs over middle finger hole. The shop owner measured the vertical thumb hole pitch and said it is probably due to it was drilled 1/8" tilted away from me which probably held on to the thumb.

I would like to know what top weight and Pin to get along with drill for my more speed then revs style. I was thinking between #1 drilling or #7 drilling at this website  http://www.hammerbowling.com/tech_info/detail.php?drilling=Drilling%20Instructions%208
