In reply to luke glaister:
+1 to reccing the ab, it would be quite difficult to find on your own in any bad weather. Dead easy when you know where it is.
We didnt do RN but mur 78, the climbing on west face can feel very airy for the grade but is actually relatively soft touch technically.
Worth knowing that the hut/campsite can be sat in clag but once you're up at the face/on it you can quickly get above it and in perfect conditions. A good trick is take some mini binoculars and study/memorise the route from the hut, its a big face and can be a little disorientating trying to route find when you're first in the middle of it.
We went light with 1-10 wires, 5 cams and 12 draws, and a few tat loops for threads. This was perfect.
It is also worth knowing that it is siht hot.
