I finally ran across a couple of extra buckles I had and I decided to give the cinch buckles another try. My original setup was like this, using webbing with the buckles and then a biner to connect it to the hammock like this.
I am also experimenting with a permantly attached adjustable under quilt suspension system and I am wanting to eliminate the webbing portion of the cinch buckle setup and just take the 7/64 Spectra cord directly from the hammock to the cinch buckle. I will still be using webbing from the buckle to the tree.
My question is what would be the best knot to tie directly to the cinch buckle without using the webbing that Jeff uses in his directions. I think I'm gonna need a knot that will help to keep the buckle centered on the rope and keep it from slipping off the the side, possibly misaligning the webbing that goes from the buckle to the tree.
