In reply to Simon4:
Thanks, because it isn't the usual direction I turned to UKC. Snow Ice and Mixed is very helpful for a "wrong way" description. I want to do a big couple of days - up the Hirondelles then across the Jorasses, kip at the Canzio, up the Calotte de Rochefort (the crack may be "interesting") before heading off to the Torino for some Italian cookery. I'd love to hear from anyone who has done this.
