Cursnfurs. I'm still using my version of a SLS but I don't use any hardware. It is an adaption somewhere between headchange4u's and bearchasher's. With any SLS be aware that you will be placing greater loads on the trees than you would with the 'conventional' systems. I would never attach to a 3" to 4" tree with shallow roots in soft or moist soils. They may come over on you. What I see as the primary benefit of my SLS is that the tarp is attached to the SLS and it can be hung independently for rain protection and the hammock hung later. There is a link to my version of a SLS a couple of post back.
