Telemark ski might not be designed to hold alpine heel piece, screws might rip out if you try to mount alpine binding on tele ski. Alpine skis work for me because I use big boots and I am a big person. If you are lighter weight and prefer light weight boots, you should use telemark skis. Probably they will work better for you. Also they have features like holes in the tips and notches in the tails for backcountry skiing.
With todays skis, even tele specific, people are mounting them with AT gear. My wife has a set of Rossi Megabangs (which are tele specific) and has Solly alpine bindings on them. These skis are not as stiff as the B3 (the alpine equivalent) but they make a great pow ski, actually they are a great all mountain ski.
I tele on a set of Atomic 10ex's which are alpine skis. The Atomic TMEX has the same dimentions and even look the same but they are a little softer in the tip and tail. It's all a matter of preference, I prefer a stiffer ski so that's why I went with the alpine version.
