In reply to andy farnell and Lemony:
Thanks both, very informative. Looks like it could be truly 'next level' then?
Also (to my punters eye) it looks an incredibly 'simple' line (pretty straight, consistent 45 degree overhang, not many moves, a few crimps) therefore the moves themselves must be proper hard, nowhere to hide, a pure power problem?
As I understand it, there's been some discussion in bouldering about the limits of such problems (i.e. people saying there is a limit to how hard you can pull, and 8C+ maybe almost it?), and harder problems will be combinations of different styles, or incredibly morph. Perhaps this proves there is still room to squeeze more out?
Strikes me as the kind of problem someone like Ben Moon would like.
