I'm seriously considering a switch to hammock sleeping but I have no idea what I'm in for re: weight. The hammocks themselves are light (I'm looking at the Warbonnet Blackbird). My question relates to everything else...I don't know how much other gear is required to sleep warm in the colder southeastern months. We typically avoid summer and stick to fall/winter/spring, so nights in the 30s are typical.

As for gear selection, a hammock + rainfly/tarp are a given. Do I ditch my 2.9 lb 20F REI bag for a quilt? Is an underquilt required for low 30F temps? I'd like some direction on how much gear I need to buy and carry and what I can expect as far as weight is concerned. Currently I pack a SD Baku 1, REI synthetic mummy bag, and Big Anes Clearview (uninsulated) pad. It would be nice to stay at the same weight or even drop some ounces.
