The suspension I use with my eno is:
I" tubular webbing bought at an outfitters for 30cents/foot, 30 feet, $9. Two decender rings tied to the hammock with cord ($5). I cut the webbing in half, sew loops in one end. The open end of one strap is used with the rings for adjustment and the other strap is tied to the tree with Ed Speers hammock knot. I took off the heavy biners that come with the eno and bought one good climbing biner ($7) for the end of the hammock without the rings to attach to the loop in the webbing.
