Cordelette 

So simple. Makes me wonder why I never thought of that.

I like doing a shaka with one hand and alternate wrapping the cord around my pinkie and thumb. Idk if that makes any sense, but it ends up doing the exact same thing as the seesaw method he explains at the end

6mm x 9kN edelrid PES cord should be enough?

This cordalette looks a lot more supple than mine. Is it a unique material or brand of rope?
