Hi, i don't mean to be rude but that seems very time consuming. Would it not be easier to buy a €7 light weight slim 120cm sling. Connect one end to the head and a carabiner to the other end and your harness
Precisely. Another common question is why do this instead of buying a bungee leash. Most bungee leashes aren't rated very high, my Black Diamond one is only rated for 2kN; whereas this gives you something fully rated.
