Took a bit of finding, with a couple of false starts, but well worth doing in the end. The guide says "it develops quickly into a narrow well defined crest" but it only actually does this after 50m, ie half the route. I led the 1st and 4th pitches, the last I took the arete direct rather than the ramp on the left, quite scary but only a bit harder, maybe VDiff/Severe.
