The Only suspension I include with my Bridges to friends and relatives and recommend: Whoopie slings, webbing tree huggers and the Marlin Spike. For my self I replace the webbing huggers and Marlin Spike with rope huggers and nacrabiners.
I've tried/used everything starting with the Hennessy wrap, then to all webbing with cam buckles, then rings and then all kinds of doodads for webbing, some bought, some from friends and relatives, then to rope using bowline knots, then a fancy truckers hitch with wrapped biners, then the garda hitch, then the zig zag cleat, then a rope cleat I forget the name of, then Figure 9s.
I'm pretty sure there are about 5 or 6 methods in there for webbing and rope that I have totally forgotten and a few that I refuse to mention
I have finally ended up with plain whoopie slings, rope huggers and nacrabiners. Easiest, simplest, quickest, lightest and least bulky suspension of all I have tried.
Totally field replaceable, NO hardware. As long as I have the Bridge Hammock body and a 70' length of AS-78 rope, I can make a complete replacement for everything else: suspension, suspension triangles, ridge line, rope huggers, nacrabiners in about 1 hour and can then easily hang the hammock. If I manage to lose the Bridge Hammock body, I have a real problem - still working on that one.
