In reply to rjwaterton:
Robin has also commented on UK bouldering saying -
"In terms of the grade, I suspect I was a bit over-zealous with suggesting 6c and 7a is likely the correct grade. In previous discussions with Malcolm I think we agreed something like E8 / 7a / 8b / 7C+"
I enjoyed this article, great to read so much about so few moves. It means something.
