In reply to John2:
I think it was upgraded when a substantial piece of the cliff fell off many years ago. The picture in my copy of hard rock is totally different to the way it is now !
Pitch 1 has the crux which is getting established in the niche before the overlap - brilliantly protected throughout by small (1s and 2s) wires. Pitch 2 would probably get HVS 5a on its own and it is superb.
Kittiwake is a good HVS with some real climbing wall style jugs.
