In reply to Stig: Yeah think that's it. As I said, it's called 'Guppy Arete' in the BMC guide, at V1 on the left, and V2 on the front/right. It's got a step in the ground at the start of the problem, and if you climb it from above that, on the left hand side of the arete, it's about V1. The way I climbed it, starting below the step, it had a cool move rocking around onto the front face. I remember a long move on the front face to reach a jug on the arete, and then I finished up the V1 (left) side. This was about 6b+. I don't see where the 7a+ goes - especially since the front (RH, slabby side) gets V2 in the BMC guide (but that seems like a massive sandbag). The BMC also has a sit start at V6 - is that the 7a+ "classic arete" or what? (But if it's a V6/7 sit start to a V2 arete, it doesn't sound very classic to me...).
