I read through your list and most of the responses. Wow - that's quite extensive! I take it you're a man who appreciates order and due process. I'm right there with you brother, but I also like to live on the edge. As the years go by I find I'm becoming more and more adventurous.
My packing list is substantially smaller than yours though it still contains everything I'll need for the 7-day span. I'll be taking the absolute necessities sprinkled with a few surprises. Seems I've become quite adept at squeezing 6 gallons of water into a 5 gallon bucket.
My bag of choice will be a full sized Samsonite and I suspect I'll be able to fit everything I need with room to spare.
Packing lists will vary from passenger to passenger. I would suggest, to one posing the question, to start with the "givens" and then add to those as space and weight allow. And also to take some time to do this. Packing at the last minute is what gets us all in trouble.
Controlled and deliberate input, lest you chuck it all away!
