So my time and money is better spent finding a correctly fitted well-made saddle for him instead of dealing with the whole "custom made" thing. Cool. I have an old Bob Marshall Treeless, but I'm not sure how I like it for him. It's pretty worn and I'm concerned that it might be causing some back issues.
I do ride western right now. Well I have a western saddle anyways. Trained english, so I'm trying to figure out what the real differences are (besides the whole, neck rein, direct rein issue). That's a whole nother thread though! Thanks for the help guys.
