I personally love the torso length wide NeoAir Trekker.
It doesn't crinkle, it is wide enough that my whole upper body is on the pad. So no cold arms when I'm sleeping on my back. It is super comfy.
I supplement with a piece of closed cell foam for insulation under my legs. The closed cell foam also acts as my pack frame. I usually go with 1/8" to 3/8" thick depending on the climate.
