Thanks everyone for the welcome and tips!
This is what I have so far-
Continuous loop through the gathered end to a dutch hook to a whoopie sling to a tree strap.
If I were to add a ridgeline, where would I attach it? The continuous loop? Through the gathered end? At the Dutch hook? What works for you guys?
Also, when it comes to material, what kind of stress will be exerted on the ridgeline? Will 1.2 Tech line be strong enough or do I have to go with something like amsteel blue or dynaglide?
