DMT, you should go and check out some of the newer Tele stuff available these days. It's no longer on waxless skis with metal edges or three pin bindings.
Wed are talking serious four buckle plastic boots, step in bindings, tour/ski mode bindings and all that shazam.
I know what you are talking about the older gear from the 90's and stuff, I know my dad used to tour on that kind of stuff, and you are right. That stuff is not ment for big lines or such.
Plus, you know, you can still parallel turn tele skis too.
All the same ski moves you do on AT can be done with free heel bindings.
Anyhow, I was suggesting that the OP would most likely save quite a bit of money starting out with a decent tele set up (and I am not talking about some old three pin deal eaither) than dropping a mountain of cash at some Dynafit set up.
But what do I know, I prefer to ride a Splitboard...
