I don`t think Equilibrium is in the E6 to E8 bracket unless mister Gresham down graded it!
The Knock is probably V2.
This coming from the "obsessive maniac". Hmmm?
Yeah ! It's time for another grading conversion chart, this time we have route/boulder British Tech Grades.
You can do it in a round about way, just look what French grade is gets on Jon Read's site, then use the Rockfax table for boulder traverse grades to get a V/font grade. I recon it works for some routes, probably the bold technical non-pumpathon type routes
