I must carry about 50m of paracord in 2 25 m lengths.

I also carry a roll of jute garden twine in my bob for the times when i am not going to retrieve it or I just do not want to waste paracord. It also means I can make slings and things with it.

snare wire enough for two in my kit and about twenty in my bob.

Duck tape just seems to bred, I try to keep about 10 meters but always seem to have more, i.e. a roll keeps finding it's way into my bob.
