In reply to gravy:
Super aesthetic narrows it down to a pretty small handful of crags. Does raven tor even make the cut on that requirement?
I've never made it there but the diamond on the orme does sound like it fits the bill. And Goredale of course.
Specific route wise, I:d say the best 7c I've been on in the UK (if we take looks into account) is probably dominatrix at Kilnsey.
Edit... Oh hold on the ashes is there too. Hmmm. Tough one.
