In reply to graham F:
Or you could camp overnight slightly illegally which is what I intend to do. On reflection the longer rope might give me options if we retreat down the ridge to the Col de tacul rather than the lower traverse which is a bit of a death trap really. Can't remember if the Moran book says there's stanchions but anything is better than playing serac roulette IMHO. Thanks for advice.
BTW, pushing my luck here but if the Kuffner is too dry is the Arete de Diable still a good option in dry condition? We're going slightly late season for my liking (end of July), but alas one of my climbing partners has a life and can't just go whenever, like me....
