In reply to Exile:
Would agree with iain that the traverse left out from the chimney could be easily missed - this was pitch three as we did it but they were quite long pitches!
I also remember the line for the final 50m being a bit vague after you get to the point overlooking the gully, once we got there it was just a case of following our noses up the easiest line to the top.
