i have been running this through my head for a while.
in effect this is one loop of line adjusted by a ucr(backwards whoopie when used to form a loop?)
1 can use trees closer together,when comparing to whoopie slings.no bury between hammock and tree
2 after attaching tree straps,only one adjustment to make
3 after everything is tight can slide hammock anywere between the two trees,adjusting its position without loosening anything.
4 biult in structural ridge,hammock hangs the same every time.
thats my idea.has it been tried?please tell me what you think.i have rigged one up and plan to try it tonight in the woods.hopefully it will not let me down.
