Red - if this is true (Kong Duck) then a 12-18mm 120 cm nylon sling may very well become my tree rope. Just loop it around the tree, thread it through itself and you now have a sling instead of a rope. Advantages - compact, easy to store, stronger, easier to move around tree and lighter. My wheels are already turning on using a sling for both lineman's belt and tree rope - going to be busy this off season for sure.
Sorry Dave, I responded to this this morning but I guess the post never went through.
I had the exact same thought as you, that is why I bought the duck. I have a 240 cm dyneema runner at home. I tried it out and man is the system light and compact. When I tried it I left my rope strap hooked up and just slightly loose so I could safely make sure it worked. Now that being said, I haven't been willing to integrate it into my system yet. I did some research on these nylon runners and the problem with them is there is no protection on the outside like a climbing rope so they are prone to getting nicked up, and then when they fail they fail. A small area of damage could be really hard to spot. I can't justify saving a few ounces on the most important thing between my saddle and the tree. I'm still looking into other options to make something like this work, and if anyone has any ideas or thoughts please share.
