In reply to Tom Ripley Mountain Guide:
A long while since I did this but the grade at the time didn't seem unreasonable. My log notes that I took a long time on the hardest moves.
Of course it's possible that a hold has come off but I reckon the problem is this... you're too good a climber.
That rising traverse can be done in a number of ways using different sequences of holds.
If you're a good climber you find a sequence that works, climb across and go, blimey that's hard for E1 5b, closer to E2 5c.
If you're an E1 5b climber you fumble about until you find the only sequence that works at E1 5b, climb across and go, that took me ages to sort out.
