I just went through this process as well. After a lot of thought, I've decided to go for a self inflating mattress, self inflating pillow and tent, as well as a decent sleeping bag. I know it's not the answer you were looking for, just throwing another option at you if you haven't already thought about it - apologies if you have. I can never get a good nights sleep in a swag, guys with this setup swear by it and setup time will surprise you. If you decide on researching this sort of setup, google the following:
Oztent
Black wolf turbo tent
Thermarest luxury MAP self inflating mattress
Thermarest pillow
Coleman c5 sleeping bag. It's big so you an toss and turn.
This setup is quite compact as well. Good luck and let us know how you go.
