In reply to AMorris:
I agree, I'm sure its a difficult thing to slap a number on, and the breakdown is useful and perhaps more impressive than simply saying 8B+ or whatever. However despite how difficult it might be to grade, Alex has offered a grade which he describes as the consensus - and that grade is 8B+.
I'm not a great follower of Wheelbarrows' activity or of elite bouldering in general, but I do know that Alex has a pedigree of using knee bars and pads on hard stuff (something that I fully support) and proffering sensible alternative grades for ascents made in such a way. To report these ascents with the original higher grade is disingenuous and will only add fuel to the fire of the anti-kneepadders, which can only serve to hold back the future of hard climbing.
8B+ or 8C, it's still a fantastic achievement for Alex and he's clearly very satisfied with the climb, regardless of what grade others choose to cite. As such this is not having a dig at him, moreover a plea to UKC to make their reporting a little more honest.
