In reply to tinks:
Here's 10 to be going on with:
Forbes ridge - Aig. du Chardonet
Frontier Ridge (Kuffner)- Mont Maudit
Brenva Spur - Mont Blanc
Frendo Spur - Aig. du Midi
Diable ridge - Mont Blanc du Tacul
Rochefort arete - Aig du Rochefort
SW Face - Dent du Geant
Aiguille du Moine South Ridge
Hirondelles Ridge - Grandes Jorasses
NE face - Les Courtes
These are all established classics so don't expect to have them to yourself (except perhaps the Hirondelles?) but that's Chamonix.
There's a bit of a ridge theme there, but classic routes at that grade tend to be ridges. There are plenty of classic rock climbs which used to get AD/D etc but as they're all done in rock shoes these days they tend to get rock grades now.
Get yourself a copy of Gaston Rebuffat's "100 classic climbs" for more ideas.
And finally, here's a recommendation for one route NOT to do Moine Ridge - Aig Verte. Whatever any guide book tells you, just don't be tempted!
