It's a shame you went with the DAM if you were concerned about moisture. I use a BA insulated air core that is synthetic and has a 4.1 R value. Even though I'm 6', I got he petite which is 66" for the weight savings. If I have to go to ground, I just put my pack under my feet. In my hammock, I don't need the full length.
That being said, I use both an UQ and a pad when it's below 30. I put the pad between my hammock and the UQ. I've used that combo with a peapod and -7 F was fine on the bottom. My No Sniveller and the pad had me warm at 15. If it looks to be colder than that, I bring my Huskie-Shepherd in my hammock for an extra 20 degrees.
