2) Tied with the figure 8 but already knew I wanted to get the carabiner rapeling rings setup for quick setup and adjustment.
I recommend against this method. The rings will over time damage the rope which could lead to butt meets ground. I have a Hennessey set up that way and I can see damage, it hasn't broke yet but the potential is there. I recommend either whoopie slings or if you really like the rings and biners method then attach the rings to the hammock and use really long tree straps and run those through the rings.
Oh and welcome from North Ga!
