Hey Mr., I just had this ball drilled. I might be able to help you a little.I'm not as up to date on new stuff as others are.I have my ball drilled between #1 & #2 on the layout sheet.My pin is just to the right of my ring finger and the heart is just to the left of my thumb , with half of it drilled out.My pap is 5-1/16 right,1/4 up.I throw it with the oob.I slide at 18 and throw at 8 out to 5 and have no problem with it coming back.I'm just getting back into it after 17 years , so I can't give you a whole lot of feedback yet.I'm still learning the new age bowling. Mike
