But you need to show him your style of play, and what conditions do you want the ball to be played under. Usually, the first ball he drills for you is not up to expectations. But it gets better and better with every ball.
I think the above can be said of [b[all[/b] drillers. Btw, the "triangle" is always between the PAP, CG and pin of a ball. CG is not even that important these days. Pin and PAP distance is the lion's share of the ball reaction equation, all things being equal.

I don't think it is too wise to keep changing drillers for the reasons which you quote. For instance, when your ring finger was stretched you should have gone back to him and worked the problem out after explaining to him.
Folks, there're a few things to getting a driller:
1. No one driller works for everyone. It is important to have chemistry with the person who translates what you want to what you get. This is simple to understand.
2. You have to discuss what you want and what to do to accomplish those objectives. And i don't mean objectives like, "more hook" or "hook later". You don't have to be a technical guru to describe what you want. Here are some examples of things you can work out together - where you want the weight of the ball to sit in your palm, how much slack do you want on your span, et cetera.
3. Ball drilling is an art. Unless you are buying a ball with a very complex asymmetrical core design, you can pretty much throw the drill sheet away. And forget about how many inches your CG is from the PAP or how large is your balance hole or stuff like that.
All these are numbers. Statistics. They are for reference and hold true only for a ball
at rest. Once you throw a ball, dynamic weight takes over the static weights. And good ball drillers know that there is no way in heaven any machine can even measure dynamic weight as it changes. If you are at a driller who is obsessed with static weights, you better move on.
This means that your driller is trying to match
what you tell him to what you want. It is guesswork at best. That means the bowler and the driller must both discuss solutions. Nobody gets it right first time.
All this means a good ball layout comes from committed and accurate feedback on the bowler's part (since the good drillers are asking anyway). More often than not, it's the bowler who supplies bad input to the driller before blaming the driller.
P.S., I made a minor adjustment to the way i throw the ball two years ago. That meant my grip was no longer the way it was. To get the best possible feel, i used an old ball to plug, drill, and re-plug to experiment with different layouts. During that time, I spent up to three hours during every re-plug session inside Walter's shop doing nothing but discussing what changes to try next. And we're talking about changes the size of one-eighth of an inch per time. (Like everything in bowling, make changes one-at-a-time to find out which one works). We drew diagrams, discussed my hand's idiosyncracies and played with pitches, et cetera. And we didn't even talk about ball weight layouts because that changes with different balls.
5 layouts later, I found the layout that I am still using till this day. And all my balls have since been re-laid with it.
