Solus;
"This year a friend convinced me to try an Exped. It has an integrated pump (not as hassle free as the thermarest but much easier than the Big Agnes). It is more comfortable than any pad I've used, but considerably more bulky than the Big Agnes. It is amazingly warm. On my last outing I had quite a few nights in the twenties but used the bag only as a blanket- to get into it was to roast. "

Could not agree more! The Exped 9 makes the optimistic BA temp  ratings closer to reality.  The combination of the Exped9 and a BA Lost Ranger is good to 20 degrees for me. With the Insulated Air Core BA pad I was chilly at 40.
