In reply to WJV0912:
> Is there any chance you could post what you think would be a good itinerary for acclimatization then a Mont Blanc attempt?
Assuming you want to stay in the Chamonix/Mont Blanc massif area, not to consider anywhere much else (the Grand Paradiso is obviously not in the MB massif, but not that far away) :
A possible first outing would be (does involve starting from Switzerland and not getting back to your startpoint)
Day 1 : lightly equipped, walk up to Cabane du Trient, spend the night at 3170 m.
Day 2 : cross the Plateau du Trient (obviously glaciated, but not likely to be badly crevassed), cross the Col du Tour (3282), descend toward Albert Premier hut and then to Argentierre.
Day 3 : easier day, to allow your body to adapt to the challenge of altitude the previous day (something like easy cragging in the valley, or possibly catch a cable car up to the Aiguille Rouge and do a rock route up there, with a superb view across to the main MB massif.
Day 4 : Mont Blanc du Tacul from the first cablecar, then down
Day 5 : rest in valley, let your body adapt to the altitude
Day 6 : approach one of the MB routes
Day 7 : route and hopefully down the same day
Allows not much margin for weather, buggered-upness, huts being full etc. As I mentioned, Aiguille d'Argentière is an alternative to Tacul, at 3900 it is reasonably high but not as high as Tacul at 4250. You could substitute the Domes du Miages for the first route, starting from the Conscripts hut at 2600m, also allows the Aiguille du Tre-la-tete at 3900m. It would be possible to spend 2 days at the Conscrits, on day 1 do the Trelatete, on day 2 do the Domes traverse. The Aiguille des Glaciers is also an option from that area, but more obviously from Italy (Robert Blanc hut). Doing 2 routes from the Conscrits means you get more route bang for your hut-approach buck. The Dome du Miages traverse is said to be a magnificent classic expedition, but not too hard, in a relatively remote part of the massif.
So there are some initial thoughts for you! Not fully worked out, I would spend a fair bit longer working out route details, escape routes, etc if I were doing these myself (apart from the bits I already know).
