Okay, going to try two foam pads. Just "Frankenstein-ed" a Z Lite Sol to 25" wide (increased its weight from 14.5oz to 18.1oz). All of my other pads are around 25" (not 20"). Will do the same thing to another. Like you said, Its also nice that you can fold foam pads to double the insulation under your torso. I guess could also go to a single Z LIte (bomber) and the (air) XTherm Max if I really can't stand sleeping on the foam pads. Seems stupid but maybe use the foam pad as a dog protector on TOP of the air mattress.
