Well, adding adjustable shroud lines to each end of my cuben hammock transformed it from uncomfortable to very, very nice, so I decided to go ahead and add an insulating layer. I also figured I'd try my hand at an ultralight hammock, since I had such a good start. Top to bottom, the components are:
(1) Hammock bed of CT1K.18, which is about .75 oz/sq. yd.
(2) Baffles of CT.3K.08, about .33 oz/sq. yd. and about 5 oz. of 900 fill down
(3) Bottom layer of CT.3K.08, about .33 oz/sq. yd.

It's fastened together with 3M VHB Adhesive Transfer Tape, PC 9460 + Primer 94. The shroud lines are 200 lb. test Spectra fishing line with whoopies for individual line adjustment. There are 18 lines attached to each end of the hammock bed. Each attachment point is reinforced with a 1" long piece of 1/8" diameter carbon fiber tube.

The hammock alone weighs 15.4 oz. With Dynaglide suspension and assorted Dutch-bling (2 biners, 1 ridgeline biner, 1 ridge light), it totals 17.5 oz.

My top quilt and tree straps are now looking entirely too heavy. I may need to make new ones.

Pictures tomorrow.
