Glad nobody told him about the Dutch ware, then he would really be in a pickle............
I also have the whoopiesling.com tarp ridgeline with the knotbone tied on at one end and a fig9 on a sliding prussik on the other end. Knot bone end around the tree first, run the line out and then set the tension with the fig9. My tarp slides along the ridge line on 2 prussiks and small s-biners. I think this sytem sets up super quick and seems less fussy than my 2 line set. The prussks don't even count as a knot. Granted, I am currently switching the hardware over to the Dutch goods, but it is the same idea.
I am currently using this as my guylines - no slipping, light weight and they don't have that metal finger thing to tangle up my lines or possible poke a hole in my tarp.
(Sorry if you have already seen this)
I am beginning to think half of the fun hammock use is trying out the different setups.
