In reply to David Coley:
Hi Dave,
Obviously conditions dependent. For a climber of your calibre here are a few ideas:
Royal Traverse
Frontier Ridge ( Kuffner ) on Maudit
Migot Spur on Chardonnet
Whymper Couloir on the Verte
South Ridge on the Moine
Mer de Glace on the Grepon
I think you've done the Republique?
Lepidopteres followed by the normal route on the Peigne ( or Papillons and the Peigne if travelling fast )
Midi Plan traverse
Rochefort Ridge ( add Dents de Geant )
If the weather looks iffy consider basing at the Torino hut where there are many short less committing routes to fit into weather windows such as Entreves, Tour Rondes, Marbrees, Toules, Roi de Siam
Several great quick access routes on the Tacul North Face such as the Contamine routes - check out descent conditions on Tacul as you may need to descend by abseil via the Chere Couloir
To my shame I don't know the Italian side but supposedly awesome routes there, I'm sure someone will come along shortly and mention their highlights.
Might see you out there...
