is this based upon your experiences with dieter? b/c that's not what i have observed with him, or any of his employees. dieter's all about very snug-fitting boots, and he let people know that. now, that's not to say that he works with what the customer wants. there are people who want a race fit and those who don't (like folks who ride park, aren't very aggressive, etc)....you can't fault a boot fitter for working with people's preferences.
buckmans, on the other had, yeah i've def had bad stuff with them. i didn't get fit by dan, but some kid there that didn't really do too much other than measure my foot size and ask for how much i wanted to spend. i had really sloppy boots from them. we do plenty of shopping at buckmans, but i'll never go back to buckman's for boots.
OP, here's another tip....don't feel like you're tied to one boot fitter. i think it's important to do business with someone you get a long with and feel like you can trust. if you go to a guy and you just don't click, then maybe he's not the fitter for you. everyone's gonna have their favorite (or least favorite) boot fitter. but in the end, most of them are technically competent.
