In reply to beardy mike:
> So far Lynn Hill, Scott Backes*, Tommy Caldwell ** and Jorg Verhoeven, I think that's it, have freed the great roof and changing corners.
* Scott Burke (not Backes) toproped cleanly the Great Roof pitch, but did not lead it. That said, it's a traverse, so perhaps the term "toprope" is a bit misleading.
** Tommy 1st did a team free ascent with Beth Rodden, on which each pitch was lead cleanly by one of the tema and then seconded cleanly by the other. Later Tommy blasted up Nose in about 12h free climbing every pitch.
