The other thing I did, not a pack mod, was to store everything in bags. Ziploc, silnylon, etc. It makes it easier to just grab stuff (like all my food in one, stove stuff in another). With a bag this big it's easy to lose things if you put them in loose.

I like the silnylon bags best because I can pick different colors. For example, to get at my first-aid gear (used it a couple times for myself and other hikers) I just grab the orange bag and it has everything.
Life should not be a journey to the grave with the intent of arriving safely in a well preserved body, but to skid in broadside, thoroughly used up, worn out, and loudly proclaiming Wow! What a Ride!
