I was looking into building a bridge hammock but came across the old military jungle hammocks and other flat types of light weight hammocks with bars on the same plain (not sure of the right word) as where you lay. is the main advantage of bridge hammocks are better balance? Why would I rather have a bridge over a flat hammock? I look forward to hearing from you bridge builders as to why you chose the bridge over a flat hammock. Please correct me if you know the official name of flat hammock.
I've provided a link to a picture of a "flat" hammock.
