Tested The Marlin Spike Hitch At Riverbend Forest Preserve
It worked great on my Hennessey hammock, which has a fixed and integrated ridge line. Notice that I used one for the tree strap, and a second for the Hennessy Ridge Line--no knots. Thanks to Professor Hammock on Youtube for showing me how to do this. Had just 90 minutes to hike in, find trees (dead), and get it all done, then had to pick up my son and drive today.
