In reply to featuresforfeet:
Would agree with cathy on the one she sugested,have done it a couple of times with clients and we have a great time,good huts and some brilliant ski'ing,also worth looking at is the west oberland haute route,good fun to be had by all on that,and some good huts along the way. maybe also worth a look if you have'nt been there,you can do a few one day type tours from the Grand San Bernard monastry, you stay in the monastry,very interesting place,then go ski'ing the next day,theres a three or four col classic from there,but its better if you have a second car droped further down the valley.
Good luck
