This seems to be a short v. tall rating. Tall climbers find no trouble going out and up above the roof before clipping the 3rd bolt, however not being in the tall category, it scares the hell out of me going to the bolt with such an extreme fall I've taken below on #2. It is not fun. I can only guess that tall climbers can stay low on the roof edge holds and extend to the bolt. I cannot come close to that and hang the draw.
warmed up on TR.
Quite frankly, the placement of #3 is one of the worst placements of fixed protection I've experienced in Austin. See John Hogge's new climb to the right of it for proper placement of a bolt over a roof. I've fallen on it with no big deal on landing.
Update 2013/02/27: 4 years later and there is finally a proper bolt to protect the fall at the crux.
