Well I bought some today not because I'm a fan but because the guy who ran the shop I was in did me a favor and I wanted to help him out. Bought one of my boys a recurve too. I'll giv'm a shot and see.
Believe it or not (the shop owner didn't either even after he spun it on the axle) the top cam bearing in my Hoyt pro tec went bad and started chewing up inside. You had to squeez the bearing between your fingers and turn the cam to feel it but once you did there was no mistake about it.
I dislike poor customer service myself. Ya can't really go by an email though, but companies that do a good job with their emails get bonus points.
