I'm in Gaithersburg if that helps. I have an ENO double and a Warbonnet Blackbird 1.1 double layer. I'm not much good at figuring out what works for others, but you are welcome to try out my set-ups.
If your UL is going to work you, it will likely take a bit of fiddling to get to a comfortable lay. I still think things feel slightly different each time I set up, sometimes more comfortable than others, but always better than the ground (for me).
