In reply to mctrials23:
The La Sportiva legends comp is a good way for a reality check on indoor bouldering grades and illustrates why such hard grades aren't necessary.
This invite only comp is for six of the world's very best boulderers. The real cream of the cream. This year it was Adam Ondra, Alex Megos, Jan Hojer, Jimmy Webb, Daniel Woods and the relatvely unknown Jernej Kruder. The competitors get to work the 5 problems on a day before the actual comp so they know the moves in advance. On the comp day they had 3 tries each with some rest between tries. Only Ondra managed to complete all 5 problems. Megos was fairly close. Interesting was the fact that grades given were between font 8a and 8b. So if the world's top boulderers can't complete routes like that after practice on a previous day then you can see why such grades aren't needed at bouldering walls.
