In reply to GridNorth: To be honest, I can't see why anyone would want to.
Two attempts for me, both in summer, years ago - I gather it's just climbed in Winter conditions nowadays - with my high point being the Brittle Ledges. Both resulted in typical epic storm lashed, waterfalled, avalanched and stone bombarded retreats (the 2nd resulting in 2 nights stuck at Death Bivi) and almost killed me too.
It is awesome, dramatic, unique and morbidly fascinating.
It is also the most disgustingly unpleasant, horrible piece of rotting loose 'death on a stick' choss on the face of the earth, with crap climbing, following a line which wanders around like a pissed student on freshers week, and is ideally suited to either masochists or cavers.
I would sooner perform root canal surgery on myself, without anaesthetic, using a black and decker drill, than ever step foot on it again.
I even refuse to go skiing at Wengen, because the sod is always in your face
