I like things that need to move, to move, and things that don’t need to move, to not move. So I might use a whoopie sling as a hammock ridgeline just to get the length I want dialed in. Then I’d replace it with a fixed length line of the same size. I use continuous loops on my hammocks going to rings (water break and connection point for main suspension without line-to-line contact) and larkshead the hammock ridgeline there.
