Tried another suspension system, and I think this is going to stay on the hammock.
Ordered from Arrowhead Equipment a pair of ultralight cinch buckles a pair of polyester suspension lines (13' each strap) and used a set of "dutch clips" on the straps at the tree.
Hung it last night pulling it fairly tight (I don't use much sag when I hang, just prefer it that way because of my back) and never had to make any further adjustments to the suspension. Very little stretch to the straps, the cinch buckles held very securely, and it was easy to set up and take down.
I think I've finally found a hammock and suspension system that pleases me!
Got my 3/16" cc foam in the mail today, cut it somewhat shaped to my form & size (rounded at the head & foot, and a bit wider than normal at the torso area , but I may shape it further after I use it) and now I'll have to spend another night outdoors to test it's performance.
This equipment testing requires a lot of time in the outdoors for my son and myself, but we're enduring it well.
