Hey,
For the 5-10% who climb at Welsford that have been on this route (I may be exaggerating, it may be less ), I added a bolt to eliminate the deck-fall potential between the 3rd and 4th bolt. This is a sport route so in my opinion there was no need to have such a run-out. I communicated my views with the FAist (Ghislain Zig) and he gave me the go-ahead. I also scrubbed it a bit... So get on it!
Also, 5.11c might be more appropriate as a grade.
The Attic is such a wonderful wall. With the addition of Hitchhiker, it makes it that much better. So if you climb 5.10,5.11 SPORT and have never been there what are you waiting for?? The cliff also dries up much faster than the Upper Tier.
BTW for the sport climbers that won't climb Joint Venture because it's mix, the route is all bolted except for the last 15ft which is on 5.5 terrain. A 0.3 BD to #1BD fits in the crack up there. Nuts would probably work as well but running it out is also not scary at all.
