I use a 35’ length of paracord with s biners on each end that I use as a dual function bow tow/rope retrieval. When I drop my bow down on one end I attach the other onto my tether stopper clip before I rappel down and then pull it down from the ground. Having s dual function rope is nice except it’s a giant pits to manage as it’s always tangling and knotting up on me. Just curious what you guys use for your bow tows and rope retrievals.
