My latest suspension exploration is recycled car seat straps and a marlin spike hitch to hold the continuous loop of my hammock. Why? The straps didn't cost me any extra and the MSH allows me to unhook my hammock easily if I want to add or remove my bug net or other accessories. And take down is super easy, unhook the hammock, pull the toggles and done.
I should mention I use a Grappler soft shackle to secure the strap around the tree for easier setup and lighter than my steel shackles.
