I've got a $50 REI gift card and am wanting to get one nice item with it. Thinking an ENO Singlenest Hammock. I would get just the hammock and make my own straps and rainfly. Any opinions on the ENO?? Should I stay with the single or get the double?? I'm 6'1" and ~145 lbs. Is there another hammock around $50 at REI that's better? Looking for all opinions, both positive and negative!
