Thanks Baggins. My mind was going a bit fuzzy after 14 hours. I had brilliant support runners but I was the only one with recent familiarity with that bit of the route. I remembered the gully being fairly solid then an easy scramble on the left edge. We must have headed up the wrong gully. It didn't slow us down much but there were lots of loose rocks and I certainly wouldn't reccommend that route to anyone else. It had seemed obvious on my recces so I hadn't thought of it as a potential error point.
