Hey Theo, weirdly I was just about to post about the exact same problem. I went looking for it last week and I think I found the right problem above LDF on a short steep wall under a bank, ie more a small outcrop than a boulder. The problem I climbed started on a juggy left-hand sidepull, went up and right to some quartzy crimps, a bit further right to a small sidepull and then up to the top of the wall. Felt about 6B+/6C, obviously I left feeling a bit perplexed and have since heard that some holds are out.
Anyone know a) whether I was on the right piece of rock and b) how the 7B+ is meant to go?
