In reply to Michael Hood:
"From this distance it sounds like he's in danger of falling into the same trap that has bedeviled UK grades - being overcautious with the next grade."
I know I'm trending a little off-route here, but I'm inclined to agree with you. I've always liked the UK trad grading system; the two pieces of information actually tell you a lot about the route. (I always remember the old Stanage guidebook's rule of thumb: E1 6a = ego damage, E5 6a = check for pulse...) I read a comment recently - probably on this site, though I can't remember - that the trad 6c grade was next door to meaningless, but that's a shame - there's no need for it to be, and if it is, one likely reason is a reluctance among cutting-edge climbers to use the 7's.
OK, I'm an ageing bumbly* struggling with finger injuries, who defers to anybody who climbs French grades with numbers bigger than 6. But it does seem improbable to me that there are climbs covering every E-number from 2 to 10 that are all given 6c.
Meanwhile, back at the ranch - hats of to Ondra. And not for the first time.
