Update: The Big Agnes Rapid SL 25 x 78 just arrived. I blew it up with the provided inflation sack. I tried it out, rotating between it and the Thermarest XTherm Max Large and man what a difference. So much more support and comfort with the Big Agnes Rapid SL. I'm pretty sure I could sleep through the night no problem on this. I actually prefer it fully inflated which is weird, I though I would like it deflated to 85-90%, but felt like support suffered when I tried this. Things might change when I try it overnight. With the XTherm, I could feel my hip on the hard floor. For lighter guys this might not be an issue. For a 6' 225 lbs side sleeper, I could feel it.
Still waiting on the Sea to Summit Ether Light XT to arrive. Should be here Thursday. We'll see if it can get any better.
I think I might be able to find a better pillow as well. I'll be testing some other brands. Stay tuned.
