One thought: I have found that using thinner lines has more of a tendency to "cut" things is comes in contact with. I think HE said something about thin support lines damaging his hammock. I used some really small line to secure my HH top cover when I first made it. I had it tied through a webbing loop and when I pulled it out it actually cut the webbing like a hot knife through butter. If you are tying on to the original HH Spectra you may not have to worry about that.
I think Jeff also said something about that on his site.
