I'm putting together my hammock rig and someone just gave me a gift certificate for REI. I thought I'd use it to get a Noahs Tarp - but I am undecided whether to get the 9' square or the 12'.
I have been leaning toward the 12' since I plan on purchasing a Switchback within a month or so, and they recommend a tarp with a 12' ridge line. However, after scouring the forums, I see a couple of people have commented that their 12' actually has a 16' ridge line. That is huge, and some say it is more of a challenge to find trees that far apart.
Thought I'd throw it out to the hammock-meisters on the forum -- would the 9' square Noahs Tarp be large enough for the Switchback, or should I get the 12' square?
