In reply to dgbryan:
Although most of the comments the other poster has made are totally valid, I prefer a more positive outlook!
I've done a reasonable amount of skiing in my spantiks and 130cm skis, and I think for the right objectives and snow conditions its a great way of getting in out of routes provided you are a strong skier. ( although some of my friends will definitely disagree).
Although you can climb pretty hard in ski boots, I don't really like it, and my proper skis are 185cm which really get in the way, so i prefer having a proper ski set up and my approach set up.
most modern bindings wont fit mountaineering boots, but a lot of old school metal touring bindings will. Silveretta bindings are the cheapest, although are rather heavy. A friend of mine uses some nice lightweight plastic things that are a lot better, unfortunately they are really rare, and I cant for the life of me remember what they are called.
Generally as long as the snow is consistent its fine, if there is any wind crust you are totally f*cked. I've skied out from the jorrasses in knee deep powder, skied back out from the courtes in cruddy snow and both times they were great. I've even had a few piste days on them for fun ( but you look like a total punter).
It is a very easy way to blow your knee out or break and ankle though due to the lack of support in mountaineering boots though.
