In reply to Blue Straggler:
Condition of the bolts has to be taken into account. They're old 8mm aid bolts that have been there since the 80's at least (anyone know?), so the line in the article that collectively they might provide a soft catch (i.e. they're not great and the belayer is going to have to help reduce the impact) is what needs attention.
Okay, they've taken one fall, but that's not to say they'll take another! Someone mentioned Parthian Shot earlier, but I seem to remember a discussion about clipping pegs on London Wall and what grade it should be at about the time someone ripped the pegs and fell to the ground that might be more relevant.
So it could be E8 if the old aid bolts are brilliant, or it could be E10 if they turn out to be questionable.
