Greg: I haven't used the blizzard bag yet, I was planning on bringing it with for an over nighter in addition to my heavy bag so that if it doesn't work out I have a back up and then I can re-evaluate my plans for sleeping.
I plan on hiking in the summer in the mountains of Utah mostly, with lows at night in the mid to upper thirties. The base layers are mostly for sleeping in to extend the warmth of the blizzard bag. I'll be wearing a t-shirt, running shorts and minimalist trail runners, and maybe put on the polypro if it gets cold unexpectedly, but since it rarely drops below 70 until the sun goes down I should be ok. I'll check out the dri-ducks.
Luke: I'm definitely looking at flash lights, the big reason why I like the headlamp is for setting up in the dark, but if need be I can also attach a flash light to a hat or hold it in my mouth.
M B: I'll touch on these one by one
Shelter, groundcloth, stakes: From my research the blizzard bag is ok to be used on it's own without shelter or ground cloth unless you're expecting rain, my schedule is loose enough that if rain is in the fore cast I can go the next weekend.
Fuel container: I'll be using esbit so I wont have a special container for fuel.
Aqua mira: For some reason the drops just don't seem right to me, I like having a filter, so I'm using the lightest I could find.
Light: See above.
Extra underwear: I like having an extra pair, but it's not out of the question.
Rain pants: I shouldn't need them, it'll be warm when I'm using this kit.
Knife: I have one of the tiny SAKs, I forgot to put it on the list.
Food bag: Hadn't thought of that, I'll probably look at an opsak, bears aren't a problem where I am so if I can contain the smell it should be safe from critters.
Thanks for the suggestions, I'll make some changes and update the list.
Edit: A search on Amazon for Dri-Ducks brought up 2 pages of results. Is this the set up that everyone uses? http://www.amazon.com/Duck-Light-Weight-Hooded-Rain/dp/B00279IZEU/ref=sr_1_2?ie=UTF8&qid=1334449179&sr=8-2
