I've done it l-r and r-l : a worthwhile problem which you've rightly publicised Travs. I reckon Zaff and the cockney sparra will have done it too. Nice climbing.
I apologise to Travs - having read through my diaries recently I was off the mark.
I climbed the left to right traverse (sit start at the corner/flake) around the arete and up in October '97.
I also climbed a good eliminate that I got mixed up with 'a tricky traverse'. Sit start at the arete, up and left to share the sloping seam then two pops for dimples on the left wall, up to the slopey break and top. I called it 'slope grope' for my personal records - not for internet mockery.
I can't comment for Zaff, Iain or Jamie as they used to enjoy this bloc as much as I did. They avoid t'interweb for good reasons.
Good effort Travs on a nice link on fine rock. I'll try it next time I'm down.
