Make an appointment with them so they will have time to watch you bowl a few frames, then follow their recommendation on layout.  Since you don't have any of your specs any recommendation made without being able to watch you is worthless.  --  JohnP

Given if he's just getting into bowling, what would be the point of watching him go out there throwing a ball? his style will be constantly changing at first, watching him throw a house ball/conventional grip isn't going to tell you anything useful about rev's, rotation etc

Worrying about a layout for someone just starting out, is kind of putting the cart before the horse.

Just get a basic layout and worry about getting the fit of the grip right at first.

The key starting out is getting measured and having a proper fit on the ball.  Because there will be a lot of variables with hand position, etc with just starting out, this is probably the only case where PAP and specific layouts are not as important compared to us who have been in the game for a long period of time and know what we need.

A standard pin over ring layout would typically be the safest way to go on an entry level piece.  As the skill and technique develops, you'll then become more familiar with what works best for you.

Now with the fit, don't be afraid to tell your pro shop if you want more bevel, the ring finger to be more oval, or anything like that.  After all, you're going to be throwing the ball and you want it to "fit like a glove."  In my case, I don't have the holes beveled much, but do have the ring finger a little more oval because of problems in the past where I would tear the finger.  Ever since, no issues and it fits perfectly.
