Has anyone ever really seen a kong duck or a ropeman cut the rope in the event of a fall? I have avoided using them on my tether for some time now but practicing this year i have moved the kong duck to my tether for climbing (one sticking) and i like how easily i can take the slack out of my tether while climbing. Have been trying to climb using tether and linesman but feels really awkward climbing with the linesman up the aider. If I use the duck i can take alot of slack out of my climb up to the bottom step on my stick. Then move up the tether and step up to the top step while again taking slack out while i step up. Then reset the tether again for the next move of my stick up the tree. I have also started moving my stick only high enough to need the first step of my aider when advancing up the tree. I also use a screamer on the tether. I see alot of videos of guys one sticking with way more slack in the system than i would be comfortable with and I try to keep my rope as tight as i can while climbing. My thought is that maybe i would never really have enough slack in the event of a fall to cut/break the rope with the duck anyway.?.? Any advice would be greatly appreciated.
