It's so easy to get accustomed to something and ignore its down-side when you've not had a failure. It's just human nature!
I always carry a Thermarest patch kit for my inflatables, but also pack the redundancy of a closed cell pad. The closed cell is super-nice on top of my Neoair, whatever the outside temps.
Typically I don't carry a Thermarest when backpacking and especially when I'm in Arizona. For some reason and I think it's due to age, I decided to take along a Thermarest, this time. Oh well, next year I'll be toting a closed-cell pad and thereby not fretting about any uncomfortable sleeping arrangements on some mountainside in the middle of nowhere.
