I was hiking last weekend @ Zeleski in Ohio with my best friend and ran into a great dude Barry who recently got into hanging and really loves it. My buddy and I grilled him on the pros and con's. A lot of pro's, few if any cons. I am always striving to lighten my pack and research new products. My REI half dome is the heaviest thing in my pack. I love the idea of saving weight and adding comfort. I figured by replacing my tent and start hanging, I can take out a few items as well. I love the idea of learning a new system as well. The other thing that really pushed me to hang, my buddies snoring.
