In reply to Si dH:
It's near as the same distance to drive as the Tarn probably, just a longer walkin.
I'd happily spend all week at Boffi if I had to. I want to go elsewhere mind you, but I wouldn't object if I were forced to... I'm currently thinking of our 7.5 (ish - maybe a bit less on the last day before the flight) days I'll probably only spend a day or two in the Tarn - definitely want at least 2 in the Jonte though, hopefully one easy one hard.
I am not really intending to get stuck into a project, since personally I tend to think it's a bad idea on short trips, too much risk of not completing and adds complexity to the location choices. but if I were looking for something at that sort of grade I'd go for Sac a Glue at Boffi - everyone I know who has done it raves about it and it looks mega. Plus it's on one of the most varied and substantial sectors (Damned) at Boffi so there's plenty of variety for belayers who aren't projecting.
In terms of what is closed, there's a good post on UKB, on a thread called "Tarn - problems with the bolts" or something with a lot of info on it. On top of that, I've had some info from Adrian which suggests that sectors : "gymnase", "trone", "patrone", "diabologum", "shadocks" and also "la tour" and "zone d'ombre" are now in theory banned (although maybe still bolted) due to landowner disputes.
