I got a rappel setup this year so I’m going to be using my rappel rope as my tether. My lineman’s rope is not in the best condition so I was curious if I can use my old tether in its place as a lineman’s rope while I ascend up the tree? I’m going to be one/two sticking so I’ll be tethered to the tree but I like to also use a lineman’s rope when climbing my aider and creating slack in my tether so I’ma little more secure. Would my original tether rope suffice as a lineman’s temporarily until I get a new one?
