In reply to olliebenzie:
where are you going to be based? I would just buy that guide. each guide will have more than enough routes in to get some classics out of your trip.
In terms of bolts most of the routes in the grade your after will be mainly bolted, just the nature of the rock.
off the top of my head for Briancon side
Tomahawk on tete de Gaulent 7a+
Une infine patience on the Tenailles it 7a but you miss the 7a pitch at the top (cant be done), But some of the 6b and 6c pitches are more like 7a ( not just me saying that). Still a nice route.
Ranxerox on the set d'aval 7a+ a bit longer than you asked for 650M and a bit polished in places but a classic?
