I plan to leave the first week of March 2017. Currently I have a Big Agnes Fly Creek HV2 with a Thermarest Neoair Xlite and an Enlightened Equipment 20 degree Enigma that i planned to take on the entire trail as it can be used as a bag in cold weather and a quilt in warmer weather. After spending some time hammocking I am considering making the move to a ultralight backpacker Hennessey Hammock. I have heard many great things about hammocks vs tents when it comes to comfort and adequate rest for hiking the trail. I'm concerned about the top and underquilts paring. If I make the switch I would be taking the 20 degree Enigma, but I am confused on pairing with an appropriate underquilt. Do I need a 20 degree underquilt since I am leaving the first week of march? I do not want to have multiple quilts to exchange throughout the trip. It just becomes too pricey. Is the hammock set up truly worth it? What do I need for the hammock set up if I go that route? Any advice would be appreciated
