In reply to Ed Booth:
I remember the starting belay on this...abseil down 1 ropelength from the top, down a steep slab. Get to a narrow ledge, clip into the bolts, look round and realise that you're at the bottom of the slab at the point where the angle changes to overhanging below you. Anything dropped would not hit the ground for a good 1000 feet. Exposure does not normally bother me at all, but that did!
