In reply to scottie390: We went to do Swiis routes on Les Courtes 2 weeks ago, but the ice is very brittle at the top. Also, you would need to top out very early to make it down safely, as the escape routes are very snowy, and the sun comes up very early. We met some dutch guys who did Austrian route, and came down the North East slope, and got caught in an avalanche. Better to do this in April. NF of Ronde can be done, just make sure the conditions are good, and need to top out by 8 (start climbing at 5), as the snow will start to get slushy after that.
The descent is a little tricky to route find, but not too difficult.
Let me know if you need further info.
