Sudkante is an enjoyable route, but don't ab back down the route - too many rope traps!

Agreed - abbing down is a bad idea. I had to unstick a Swiss pair's rope after it jammed above them. However, the descent itself is quite tricky - we stayed roped until the very top - which is quite a ways from the top of the route - then got benighted during the zig-zag scree descent. Great adventure, but a long day out!
