In reply to Mark020:
When I did this back in 97', I remember climbing moss on the left wall and the crack/groove up to the roof on P1. The roof had ice beneath it, before hand traversing left.
I think this route sees many ascents these days, we had 3 runners up to this roof, perhaps the crack is cleaner now??
I would say a long, cold, dry period, less snow the better. Much ice formation on Ben Udlaidh, could be a good indicator. P3 (when iced) is visible from the road, so is False Rumour Gully IV,4, a great wee route.
