As I said in my Introduction post; I am a Rock Climber. A shoot off sport of rock climbing is Slacklining. Slacklining is basically tightrope walking with a twist, that being you jump, flip and bounce. If you watched the Super Bowl XLVI between the New York Giants Vs the New England Patriots halftime show with Madonna. The guy that was Jumpping on the rope (actually webbing), well that is slacklining.
On to my point. I think this would be a viable option. It can be used to tie into the tree huggers (also used in slacklining) to straight cordage, whoopie sling, and hugger to webbing.
Here is a video to better help you to visualize what I am talking about. You can also search YouTube for slacklining to see set-ups and see it in action.
So, What do you think. Will it work?
