Shoot, thanks for all the answers yo! One question - is 1.1 ripstop not strong enough to hold people? Aren't the single layer 1.1 WBBB's made out of 1.1, or is the name misleading me?
Also, my current hammock (Grand Trunk Skeeter Beeter Ultralight) - not sure what it's made of. Some sources online say polyester taffeta, others say "parachute nylon." Either way, I like the material, but I also haven't really tried any other backpacking hammocks.
Regarding the suspension I'm definitely in agreement that tree straps+whoopies is the way to go for light weight and easy adjustability, but I'm thinking about if I want to give hammocks to a bunch of friends - full whoopie sling suspension (or even just tree strap plus carabiner suspension) would add up pretty quick. I wondered if there's a cheaper option, even if lightness and adjustability are lost.
