In reply to Smelly Fox:
I can understand what they say about the earlier ascents - surely once you ab off a route you've lost the flash?! Same goes for the onsight.
Equally though I can understand what the yanks have said about their ascent. Say for example a route had 4 possible variations for it's crux pitch, all taking entirely different ground. (Not that improbable - a barrier wall could be split by a number of vertical grooves.) It would hardly be fair to attempt each in turn, leaving the next for another day to conserve energy, until eventually you succeed on one of them, and still claim to have flashed the route! You've got to take the right one first time and not fall off it, otherwise if nothing else you're slightly taking the piss. One could also perhaps argue it wasn't the best tactics to try to flash one of the hardest pitches on the route in the searing heat.
Still it's definitely the best attempt so far. They've done the single push thing, which a big wall flash/onsight really needs to be considering that a downclimb to preserve the attempt obviously isn't an option.
What will be very interesting is to see when the first onsight happens (it's clearly possible), and if that will be a team onsight or an individual one.
