Here's my current set-up:
attachment through the ENO channel:
the only difference between the head and foot ends is that i currently have a 'whoopie' SRL, so the fixed eye is larks-headed through the ring on the foot end and the adjustable end is attached to the head end with a soft shackle.
my tree straps (not shown) are 1/2" electric company 'mule tape.' i have no idea what the stuff is made of, but it's 2000 lb test, doesn't stretch appreciably at these loads, and i have probably 500 feet of the stuff on a spool in my father in law's barn. attachment to the tree straps is marlinspike & toggle.
i have black amsteel on order. i didn't realize that 'amsteel blue' came in colors other than blue when i first ordered. i guess i'll be selling these suspension components or passing them down to another hammock.
