closed cell pads verses inflatable pads.
I used pads before I could afford an UQ. I found that the closed cell pad worked better that the inflatable. You don't need a thick foam pad, a wallyworld blue foam pad works very nicely in a BB double. When I tried an inflatable pad I had problems with the pad pinching and or not conforming to me.
On keeping a UQ tight against the hammock I find triangle thingies do a good job of keeping my UQs tight against my BB
