After reading thru this thread, I decided to go with an Exped SynMat UL 7 Air Pad and got the Exped Schnozzle Pumpbag. I love this pad! It's such a huge improvement over my old Thermarest. Temps dropped to low 40Fs this weekend when I was camping and I was comfortable due to the R 3.1 of this pad, despite having a woefully old sleeping bag. I didn't realize what a difference the right pad could make. I also like the feel of the fabric.

I considered the MW, but got the M due to the weight. Wished they made a SW.
