In reply to phildavies84:
July / August mixed is hard to get in condition as you say.
GM ridge is meant to be really good, not particularly hard but long and committing. We got to the notch after the Carree and had to bail due to the weather coming in sooner than forecast. Downclimbed into the Argie basin - doable but a bit dicey in places and not to be recommended! It was already pretty slow going to there as there was snow on the route. So make sure you have good weather and conditions for it...
Innominata is mixed, long and committing. Staying at the Eccles you can travel relatively light.
If you're looking at rock, consider the Gervasutti. A long day route with a straightforward desert.
South Ridge of the Noire is a day route for the wads, otherwise two long days. Fair few decent bivvy ledges on the upper part of the ridge. Lack of water is definitely an issue. Descent is choss and not to be underestimated.
Cham Aiguilles traverse is a very long day for wads or more like three days for ordinary mortals. Fair few good bivvy ledges throughout, some with snow unless it's been really hot. Route finding is challenging and there are some exciting abseils. Check my log here for some tips. Check with the OHM re the state of the Nantillons glacier for the descent.
There's also the Jorasses traverse, which is mostly snow with some mixed and rock, plus a bivvy hut - which can get full! The descent is a route in its own right and takes forever.
Then there's the Drus traverse, all rock with a fair bit of abseiling. Check with the OHM / hut re the glacier approach and descent.
All of the above are fairly serious and require the ability to just keep going. Good forecast essential as well.
Enjoy!
