In reply to joe.91:
Thought about the chramoz? I've been up VS outside in them and 6b inside. They climb quite well I thought, for Scottish winter they do the job but are quite cold on belays!
As for the phantom guides they'll climb well enough, I've been up VS I think (definitely hs) and 6c, as for winter they need no explaining. The issue would be the warmth of them.
Depends what you're prepared to sacrifice I suppose.
Have you had a look at the rebel lite? They look fantastic for Alpine stuff, with a precise toe box and c-2 crampon compatible.
Maybe not worth ruling the rebel pro out though, as I found it quite flexible for a B3 boot.
