Normally on all my other bowling balls i have a high Track about an inch left of the middle finger and is slightly inverted

Well the person whose Track is right next to the finger holes would have a 6" pin to pap distance and you would have a 5" pin to pap distance and thus get more flare, we are only talking about 1" making that much of a difference and it does. I meant lower Track than someone with a higher Track than yourself, not a spinner type Track.

This is why you can't judge a drilling by where the pin is located, you have to measure from the pap. One of the guys I bowl with, he has a pin over the bridge and it is a leverage drilling for him because he has a low Track. For you the pin would be next to the ring finger for the same drilling, for me that would be 4 1/2" from my pap because my Track is higher than yours.

Since you got a thread going on here.

Where should I look for information on understanding ball drilling, pin in, pin out, various layout? I know on BTM they suggest the Bill Taylor's book but the question is.. where do I start?

Looking for guidance.

I like this site, breaks it down very well:

Is it me or do Pro Shop people try to keep simple information from you or just try to tell you to ignore the information that you wish to know?

So I follow the link cgeorg gave me since I'm a rookie at understanding ball drilling since I believe every bowler should know what the ball is going to do or should do. So I ask if I could get my PAP and I think it took a while to get it or understand it. I can do it myself now.

In general asking what ball to use, I get the speech from this former PBA Tour member that he drilled 12 balls and know what ball would be best. Should I take this advice or should I do my own research? Just curious to know. Sure, he may be cheaper in price but I don't know if I want to take his advice.

Now, I wish to know if you should know your PAP and does it matter that much to know?

The PAP is used for laying out the ball - unless you are standing there with the pencil doing the layout, you don't need to know it. That said, I would be most higher level bowlers know their PAP.

I think that a lot of drillers, especially if they don't know you well, will assume that you are like most people, and know little to nothing about equipment. Over half of the people in my last league would sand their ball to get more hook, over and over, even though their ball was overhooking, leaving splits and rolling out. I went to the Pro Shop in the center to have my Big One polished. "Wait, polish?" Yeah, I would like it polished. "Are you sure?" Yes, take it to 1500 and polish, I want more length! "Ok..." He still didn't seem to want to do it.

I now have a good relationship with a different Pro Shop. He knows that I know a little, and most importantly, I know what I want. While he probably wouldn't let just anyone do it, on my last 2 balls, he let me lay them out, gave me feedback on making sure it was drillable (not drilling through half the pin, keeping the static weights legal), and punched it up for me. Would that happen if someone he didn't know had walked in? Probably not. I think that the importance of building a relationship with your pro-shop cannot be under-estimated.

Okay.

Well, I have a Twisted Fury drilled with fingers underneath the pin which is center. Is this a 45 degree drilling as I would assume?

DJRipz, have you read MoRich's dual angle drilling system?

If not here it is: http://www.morichbowling.com/MosCorner/DualAngleSeminar/DualAngleSeminar.htm

The fingers have nothing to do with it. It's angle between the Pin-MB line and the Pin-PAP line. It's all in the link that has been posted twice now.

Hey. I have read the Mo Pinel Dual System but I am a bit lost as to understanding the graph. I am re-reading it but I am getting it in a way but maybe a few answers could help me out on this.

Is the PSA and the PAP the same distance? From what I gathered. The driller measure from the pin to the pap then angle the same distance to the find the psa.

I understand Mid-line is center of the ball and I guess VAL is the center line for the grip?
