In reply to Gwinn512:
Certainly would recommend the Breithorn traverse, it's brilliant and should go in a lot of conditions. Don't settle for the "half traverse" though, that misses a lot of the fun! We did it from the Ayas hut, which worked fine (a previous attempt based in Switzerland with a very early start from Cervinia Guides hut didn't go so well - took ages just to reach Roccia Nera...). We took the direct descent through the icefall on the way back to the hut (it's shorter, so tempting), but probably not the best idea to be honest, I'd advise going round the long way if returning to Ayas Hut in the afternoon.
Normally I'd suggest Grandes Jorasses normal route, which is superb (but serious), though I think it's dangerous at the moment.
Dent du Geant is excellent and much more enjoyable if you avoid the fixed ropes. Go up the Burgener slab a few metres to the right of the ropes, lovely climbing on little flakes. It's probably about VS, with one really tough move at the crux, which is where you rejoin the rope line so can always haul up the hard move if required (though it would feel like cheating)... We did it in rock shoes.
Rochefort Ridge too, of course.
Signalgrat looks a great route in teriffic position, though I haven't done that one.
Loads of great long committing routes on the south side of Mont Blanc (I haven't done these either) as someone already suggested; also Brenva Spur.
NB These are just a load of good routes I've done - I don't know what's a good idea in the current conditions...
