In reply to THE.WALRUS:
Hi there, we changed the wire last july and we review the abseils.
I always use a 60m rope. The first one is 25 and the second, close to 30.
If I need to finish early or there are more climbers, the best option is to abseil with 2x60, direct to the bottom of the wall. (But you need to carry an extra rope).
Enjoy the ferrata.
