In reply to duncan b:
I might be wrong but I think that after the 40m ice pitch Andy and Mark went direct up for another 15m or so and then headed over right. Nowadays you can avoid this dog leg by taking a diagonal line. Crucially though I think you have to remember that back then the winters were a whole lot colder and dryer than nowadays. Talking to Andy you get an interesting insight in to how different conditions were back then compared to what we get nowadays. The first ascent and attempts of Beyond were done in such dry conditions that we'd call them 'out of condition' nowadays. For example the 40m ice pitch which tends to be pretty amenable nowadays was really scary back on the first attempts/ascent- very dry, big falls, very hard to protect.
As is so often the case with climbs like this, if you find them in 'good' condition then it's really pretty straight forward. It's the difference between 80 degree ice which is pretty straight forward and 80 degree slabs with loose rock for pro. I'm not entirely sure if the skull and crossbones pitch is because they went somewhere different (i.e. straight up and then traversed) or whether it's because when they climbed this diagonal pitch it was just bone dry and therefore ridiculously blank and scary and run out.
Either way I'm not sure if its ever had a repeat in original conditions, they were a bit tougher back then!
