That's a solid list, Jim; good work.

My only suggestion is to elevate the priority of water purification. Water is extremely important (thus its inclusion in the Top 10 items) but being able to safely use water found in the field can make all the difference in the world. When I check off "water" on my packing list, that term means "a certain amount of water in certain containers, plus a means of purification and an emergency water container".

With chlorine dioxide you can have world-class purification with very little weight & bulk in the Top 10. Even a near-weightless sheet of 20 Aqua Mira or Micro Pur tabs can be a godsend.
