In reply to woodsy:
If you have 60m and not 50m, that'll be fine. If you have both to hand, I would take the 50m for the obvious weight/bulk/rope management issues.
Conditions on the ridge are excellent. On Sunday it took us 7 hours to the Monchjoch, and there were two ropes that did it quicker: both did the traverse in 5.5hrs [2.5 up, 3 down]. Don't forget advance reservations in the hut are mandatory. The hardest free climbing is indeed the first pitch off the glacier to the hut, but it's not too bad - maybe one pitch of 4c.
