I am contemplating using a single piece of 7/64 amsteel blue to hang my hammock. The idea is to tie the hammock directly to it using prusik knots giving me a single ridge line and suspension line all in one. I just wondered if there was a reason to tie the hammock under the line?? I'm curious because I really dont want to waste any rope I don't have to. With this and a set of tree huggers i may get to cut some weight. To me its so simple that I cant help but figure there must be a reason why its not done.
