>What happened to double ropes?
Singles got longer and stronger!
Btw, for the most part I’ve always preferred double rope technique myself, and still do.
Re spreading the force over two bits of pro, my guess is that it’s more likely spread over one and a half pieces (as a normal arrangement), obviously depending on how the pro has been arranged.
This is because in a fall the load often comes onto pieces placed sequentially and goes taught on the highest piece slightly ahead of the lower (second rope) clipped piece. |
