In reply to michaelmurray:
We did Haston Line today which was good fun at grade III ish, another party enjoyed hidden chimney just to our right at the same grade. Conditions were great today, sun shine and perfect visibility, only really windy on the plateau. The snow slopes beneath it were slightly suspect as we approached the start directly, think I would approach from the left side of the crag if I did it tomorrow (can't say for sure that would be better).
