I'll look at the claytor method tonight, thanks!
I guess I don't need adjustable on the fly, but if my newbie self doesn't get the sag right the first time, I don't want to untie knots for 10min to try again. So a knot that ~doesn't~ move once it is set, but is easy to undo if need be. The Marlin spike hitch is interesting, so is the "slippery trucker" if I can find documentation as well as the claytor.
Here is my gear list (I want to say the GT Nano is ~5 oz w/ no caribiners or suspension attached, but I don't know what my suspension will weigh so I left it a few ounces higher. I also cut off the pouch/stuff sack for the hammock):
I'm sure I need to reweigh a few things, but it's as close as it is going to get as I'm leaving Friday.
