In reply to Gordon Stainforth:
That's how I used to take it, but two routes I've done in the last few years have made me reconsider: the N Ridge of the Sirac, and the Corda Molla on Disgrazia.
Each is described as a "classic" routes in the current AC guidebook (the former, is in Rebuffat, too), each follows a good line to a remote and unfrequented peak. However, both have been badly affected by the disappearance of what used to be permanent snow, and have become loose and scary.
We spent 17 hours up and down on the Sirac. When we got back to the hut, tails slightly between our legs, the wonderfully kind and solicitous guardienne told us that the route doesn't get done much nowadays and a French party had got benighted the previous week.
To come back to the OP's question, in a curious way, although I wouldn't recommend anyone to do either route, I look back on them as "classic" days in the hills - definitely character building!
