At some point I need to address that the Big Agnes sleep system of pad into pad sleeve no longer works for me. I loved the concept, but I'm too much of a side sleeper. Taking the pad out of the bag and side sleeping leaves me cold - no insulation on bottom side of bag.

I'll need to go mummy/semi-mummy and a good pad. The Lost Ranger/Insulated Air Core was a good combo and has served me well for many years. But as temps near the 20 degree mark, I get cold. And that is sleeping in base layers, socks and beanie.
