Gonzo,
Most of our camping will be in the Southeast so a warmer/moist climate is common. That's not to say we won't get out west or up north on ocasion. I do have two nice Kelty's though if it get's REALLY cold.
The idea of a pair of mummy bags doesn't scare me too much but the parka/sleeping bag does!

The Mrs. and I are both warm sleepers, as in we create a lot of body heat on our own so we don't need a major bag to be comfortable. We often find in our Kelty's that we end up sweating even in cooler weather.
The montbell looks like a perfect solution! The Snugpack is light and inexpensive but the ability to stre--------------------tch is nice for someone like me... May have to save up a bit longer but I think it'll be worth it.
Thanks again guys! Expo portal is awesome!
