well banks did it years ago, presumably ground-up or thereabouts.
As far as I know:
Cubby top roped it first then lead it with poor rock n roller/s.
Then ten years after that, Andrew Earl top roped it first then soloed it above a pile of pads.
Then one or two weeks after that, I top roped it first, then soloed it without a pile of pads.
Then this year Adam Watson soloed it above mats, but I don't know if he top roped it or not.
There could well have been more ascents obviously, and in my opinion it's not E7 and certainly not 7c+, but I'm happy to take the grades.
