In reply to nich959:
It's possible.
Sharma put up Es Pontas, the deep water solo across the arch, in 2006 and that was graded 9b. But IIRC I think Ethan Pringle figured out a static way to miss out the dyno so don't know if that would change the grade. There was also Chilam Balam from 2003 and Akira, the Fred Rouhling roof from 1995, both of which are graded 9b but may come down in grade at some point.
Anyway great effort by Ondra. I know he tried it some years ago but I wonder how much time he spent on it recently?
Be interesting to see if he gets back on Neanderthal later this year, another Sharma 9b that he's tried and may turn out to be really hard.
