The OP who started this thread claimed to have been using Figure 9s and paracord for years on his hammock suspension. Of course, when others (including me) highly questioned the safety of that, he took his toys and went home and has never been heard from since. Post #21 in this thread was Hamster's last post on this forum. I hope he's okay and didn't have an accident using paracord and Figure 9s as hammock suspension.
A while back people were discussing using 1.75 mm Zing-It or even lighter cord for hammock suspension. I haven't heard much about that lately either - hope they're okay!
