Jim,

The underquilt replaces the pad. 20 oz. was a good weight for a pad before the NeoAir.

I prefer to use ccf for hammock bottom insulation because I can use it as a sit pad in camp. However, underquilts are more comfortable.

I think we share the amusement of theoretical gear lists that do not include stakes, guylines, suff sacks, straps, etc. needed to actually make it work. My big 4 list is a little over 7 pounds and includes everything and provides comfort on the ground. It is theoretical because I have not yet used the NeoAir in a hammock, but have used a Big Agnes Insulated Air Core. I have had the Black Mamba to 26 degrees and suspect it would go down to 20 with my normal clothes. This list is a pack with a frame and bug netting, etc.
