I saw this term on a FB page and was wondering what exactly it is?  Anyone drill their balls this way or have experience with it?  Wanted insight before I decided to spend the $12.95 that he is asking.  Thanks!!

I have sent Joe my paypal payment and have received the info.  I will be looking into updating my drilling using this information.  I am wondering if this layout will change my PAP, tilt, rotation, etc?  Will I need to modify my dual angle layouts accordingly?

Thanks!

In the beginning it changed mine radically. My pap was 4 3/4" × 0" after I went with the first layout which was 7/16" left by 0" reverse it made the ball roll over my thumb. Almost rolled over the entire thumb slug. My pap went to 6 x 5/16" up.I have since went to 1/4 - 5/16" left pitch (right hand bowler) and still at no reverse and I'm able to keep the ball from rolling over my thumb. Just remember it'll take a lot of trial and error to get the grip correct for you. I have plugged and redrilled that ball 6 times to get to what I like

I only had to do 2 drillings and have what I feel is a perfect fit. I followed the drilling instructions EXACTLY as they instruct and the ball was great the first time.  Even though my thumb-finger angle came out to 30*, my fingers weren't exactly on the flat side of grips. I Emailed Joe and he said to reduce the angle to 23-25 degrees, so I re-plugged the fingers plus increased MF lateral pitch from 1/4 to 3/8 and all came out perfect. I've used the ball 4  times since and don't anticipate any more adjustments at this time.

As for my ball track, PAP, tilt, etc. I haven't paid any attention to those things at the moment as I wanted to get the fit perfect first. Will look at those things next.

Has anyone else experimented with this technique? What are your thoughts?

I am wanting to drill this for a friend and myself. As for the thumbhole, has everyone used the normal thumb hole size or does this layout require a more tight/loose thumbhole?

Thanks for your input and thoughts.

My team mate who owns a pro shop used it for a while but switched back to his former grip.  I don't think he hated it, but didn't see any benefit or improvement with it.

Strider, same here .... I tried it an liked it at first and then things went down hill later and I ended up lowering my average, so I am thinking about returning to my old grip after our last league games tomorrow. I'm going to have to find a different pro shop though as the one I have been using is closing this week and is not taking on any more pluging and re-drills this week.

I had the exact same reaction as Ken. I only tried it on that one ball. Since then I went back to my standard thumb, but I drill my fingers according to the ADT. So I guess I'm using a semi-ADT, lol!

     I think the biggest thing is understanding what one is reading and applying the principles. IMHO I think there are a lot out there that are good, but could be great if they understood angles and applied the principles they read. If a person has a certain pitch, they have a certain pitch if that is what the hand and release are telling you. No fitting teqnique is going to change it. I have 1/4 reverse and 1/4 right lateral on my thumb and have been told I should have 0 lateral. I have tried it, it does not work. The way my hand lays I the ball and looking at my hand in a relaxed position tells me I need some right lateral. I was trained through IBPSIA and that is the system I have used for 15 years. I have read (r)Evolve and have taken it and combined it with my IBPSIA training and feel that it has givin me the best mesuring technique I could have. I have two guys that work for me and are very good drillers, but they have a hard time measuring and understanding what the hand is telling them. All of these measuring techniques are "guides".

It is understanding the difference between static and dynamic...
