In reply to Alex Buisse:
When I did the north ridge last summer the standard descent for most parties seemed to be descending the south side to the Gianetti hut (I think this is the descent referred to in the post above - it appears in the now outdated blue version of Plaisir Sud*). This means a long walk back the next day across two passes (or alternatively taxi from San Martino back to Bondo/Laret, EUR80 odd). Late in the season, though, there's no need for crampons or axe. The two guys we met on the descent who had done the Cassin did the whole three day trip with tiny sacks and running shoes.
The Badile N ridge is one of the few routes I'd consider doing again. Definitely will be getting the taxi back next time though...
*If I recall correctly, the latest Plaisir Sud has had the Badile routes withdrawn - I imagine a few people might have come a cropper approaching either the N Ridge or, worse, the Cassin, with their Plaisir hats on. On the other hand it's a shame as the topos are handy.
Hope this helps.
