Inspired by JustJeff's no modification ring buckle set up utilizing a Garda hitch.
For each end of the hammock used couple rings and some Spyderline lengths I had in my "junk" box. No need for the line if you just sew the rings directly onto the tree huggers and do the Speers tree hugger wrap/hitch. The Garda hitch allows quick and easy tensioning and centering of your hammock. Tested the set up this weekend. No slip holding my weight (I'm a lightweight). Weight for the four rings is ~46 grams.
