okay, have read back a page or two and haven't seen any comments on this yet, apologies if it's already been covered, so here it is:

SLS set up using 15' x 2" UHWMP tree straps with an Evo loop at the tree end as a soft shackle, then a mini Evo loop for a tarp line attachment point using a prussic and then an Evo loop at the Hammock end using either a larkshead or a prussic , tied off with a beckett hitch.

The tarp line is about 15' long with a loop on one end to attach to one mini evo and a mini continuous loop attached with a prussic at the other end to hook up with the other mini Evo with a couple of mini continuous loops in-between (again using prussic knots) to hang the tarp from.

No hard edges, easy to adjust and set, 2" strap holds the knots employed well, very compact/light and tree friendly
All thanks to Jeff, thanks Jeff
