In reply to paul_in_cumbria:
No, those aren't sport grades, someone at UKC Towers had the silly idea that we'd like to see higher Font grades noted in a different way to lower Font grades.
I'm guessing "font 6A+", at eight characters, is one character too long for the format of some or other page on the site.
If that is the case then I'd prefer to see "ft 6A+" adopted rather than the current mix of "font 5" and the confusing "f6A+".
EVERYONE should stop using V grads NOW!
