In reply to davkeo:
I was stopping in the Rossi e Volante hut once when a team were doing it in the opposite direction.
As an aside, they were eastern Europeans back the days when Eastern Europeans were dirt poor. The guy who seemed to be acting as a leader was carrying one of those ancient external frame rucsacks with loads of pockets on the outside. From one of them he produced an equally ancient picnic gas stove with those blue non resealable gas cartridges and then some pans with handles (like proper pans you find in a kitchen).
He was wearing a multicoloured 1980's style one piece ski suit and some bendy fabric boots.
Don't imagine any of this is of much help to you, but hats off to the Eastern Europeans who used to climb in the Alps with the worst kit you've ever seen.
