I made one a sling from air core last night. I had only 9 feet so i only have one. It works very well and is kind of addictive playing with it. It was much harder to find a single strand and get between the strands then what the video showed. His larger rope makes it look easy. Thanks for showing me this, it was a great first post. I'm going to have piles of hardware once I change out all my hammocks. Tri Glides, rings, buckles, tri rings are so last week.
