Once again wow. Jee I wonder why lineman would use it . Most knowledgeable climbers use the method of attaching a rope above your head and moving it up the tree as you climb and set your steps or move your climber. Once you get to the proper height if setting a permanent stand you just leave the rope and stay attached with safety rope and Prussic the rope at the top just form a loop in the working end using a figure of eight on a bite or such similar like a bowline.you make this around the standing part of the rope or pull the running end through the loop and around the tree. Snug it up and if using proper safety line it will stay tight. At the bottom you can leave loose or tie using any basic knot. You are right on born again.
