well, I plan to get the stuff for my DIY hammock set, eventually... it is coming along, but slowly.
any way, for TD's biner hitch, how much rope should be on the ends? enough to go from the hammock to the tree and back to the SMC ring (about 1' away from the hammock end).
I may consider more line, so it loops several times, making it like a pulley system, where it is easy to adjust but move the rope more (more accurate).
it costs $23 for a 75 yard spool of 2.8 spyderline. (hopefully west marine will have some or ship to their store, no shipping cost).
