Ya know, I've been hearing more and more bad experiences with Corbin. It's a shame too, they used to be a stand up company. I have always gone in person, so I don't really keep up with the mail order side of things.
I got my first Corbin over 10 years ago, the ZX seat is my 4th. If there was someone else local that could make me a seat like that, I'd check 'em out. If people have local options, I would definitely recommend exploring those options first, much easier to get it right in person.
