In reply to stratandrew:
It's well over a month ago that I did it, so can't comment on current conditions - however when it comes to "turning the pinnacles on the right", it's not entirely obvious. Keep looking over your left shoulder as you probably attempt to regain the ridge pretty quickly, after perhaps only 10-20 metres.
I traversed far too far. I found another team's abseil anchor after perhaps a hundred metres and from checking the UKC logbooks (after the fact) it seems it's a fairly common mistake.
I eventually regained the ridge via a steep turfy chimney which was decidedly not grade III.
Anyway, good luck.
