In reply to trystan:
Unless you have NTN boots then crampons are destined to fit really badly on teleboots. I've come to the conclusion that you need the front points to protrude out from under the duckbill which puts them way too far in front of your toes to do any real climbing in them, but makes cramponing up hard snow acceptably ok if far from "good". I just use my G12s with newmatic bindings. The front posts happen to just be about the same width as my boots duckbill so hold the front of the crampon level with the front of the boot, with front points protruding properly. It looks really stupid but works ok.
I don't have any ski crampons I seem to be quite good at skinning - I think tele boots and at least my bindings (7tms) let me push down more and engage the skin on steeper ground than friends with AT gear seem too. So I don't seem to need ski crampons as they do (noticed the same seems true for other tele skiers when we've been in mixed AT-tele groups). And then when it gets to where I can't grip I just have to carry my skis and kick steps or put crampons on my boots.
You can just add these issues to all the others that make tele gear just generally less suited to ski mountaineering than AT kit. The fact that we keep doing it in the face of our own stupidity just shows we have more soul*.
*Actually, for me this is lie. I want AT gear now - I just can't afford it. So I'll have to just keep falling down Norwegian mountain sides in my late 1990s T2 and only slightly newer skis!
