I practiced packing again tonight. I got everything in the pack - I'm only about 7-10 lbs over weight - that will be with water and electronics.
I look at a smaller pack and can't see how I could do it. I trimmed about 2.5 feet off my fleece. This will still give me plenty of length to snuggle down. The silk sleeping bag is going to be my savior - it is so comfortable that every time I test it out I want to go to sleep.
I'll try again in a couple of days to see if I can't get a few more ounces off.
Other than that - I'm rarin' to go!
