In reply to d80f0u:
Just in case anyone else is interested in the same info, we climbed the NW face of Combin de Valsorey on Friday and the conditions couldn't have been better! Mostly great snow-ice all the way, secure axe placements and enough solid ice for screws so that the route could easily be protected. Great weather too - clear overnight with sunshine and cracking views from the summit. Fantastic route!
But...
It's a LONG way, and probably at the very limit of our capabilities. On balance I think we underestimated the sheer physical demands of such a route and took over an hour more than guidebook time - this meant a late summit of the Valsorey, a decision not to continue to the Grafeneire summit and a horrendous melty epic on the way down. That's another story though.
