ill do my best to help u out some. he off sets his thumb to take weight out of the ball like a weight hole that way he dont have to have a weight hole. as far as where to put it ur pro shop should be able to fig that out may help to be in diff spots on diff balls i am not sure about finger pitches.

If I read you right, bull, it sounds like you're saying the way the ball is drilled won't make a big difference for him as long as it's legal.  If that is what you meant, I respectfully disagree.  To begin as a no thumber I would agree it's not something to worry about too hard until after you figure out how your ball tracks, how much if at all your PAP changes, and all that jazz.  After that, though, it'll affect ball reaction as much as it would for anyone else, and you'll find having different drillings as useful as anyone else would.  I bowl no thumb and although I can manipulate my ball reaction A LOT, I still can't take the same bowling ball drilled two significantly different ways and make them react even approximately the same.

 

To the OP: if you're not planning on going two-handed, I can't say enough good things about using a pinky hole.  I've found the biggest drawback to the no thumb style is that the ball doesn't always stay very well balanced in the back swing.  Two hands fixes that pretty quick, but a pinky hole does a great job if you only use one.  It also opens up more hand position options and makes it easier to change your tilt.  Just my two cents.
