In reply to NIGBEE:
The Papillons ridge on the Peigne is a good, non serious rock climb with nothing harder than VS, and not much more than V diff/severe. You can descend from the end of the ridge or go on to the top if you are in good time.
On the Italian side, the Preuss arete on the Aig de Savoie is a fine rock route at a suitable grade. You could stay at the Dalmazzi hut and try one of the long, bolted VS modern classics on the doorstep at the same time. Abseil down if you run out of time. Also from Italy, try the Aig Croux near the Monzino Hut. Very pleasant, stupendously scenic. In the Vallee Blanche there are several worthwhile, easier objectives, most with abseil descents. Consider the Eperon des Cosmiques, the Pyramid du Tacul, and perhaps the Trident.
I would not go near some of these snow and ice routes in mid summer unless it is very cool. Tour Ronde N Face and Gervasutti couloir have both seen fatalities in recent years. If you want whiter stuff, Forbes Arete on Chardonnet would be a good choice. Maybe traverse of the Domes de Miage, if it's in good nick.
Finally, when you're acclimatised, and feeling very confident, you might aim for the Kuffner (frontier ridge) on Mont Maudit. Much bigger, but not technically hard if you stay on route.
