YMMV, but at only 12 oz, I actually find the Thermarest Neoair XLite to be the most comfortable sleeping pad I have owned and that includes a huge Thermarest self inflating 5 pound base camp style pad that I tried a long time ago. If you haven't tried a NeoAir you might have a look at them somewhere that you can try it out in the store. Be aware that getting the inflation just right is the key.
