Hi Chris,
Something I learned packing bags for the medics: go BIG and go small. All of the needs that I ever encountered were either blisters or puncture wounds. I carry an assortment of blister care/band-aids, but I also carry several sanitary napkins that double as "battle wound" dressing/gauze wrap for pressure. A small squeeze bottle for wash. The rest is variations on the usual Hydro perox for irrigation, neo-sporin, pills, etc, however, I still believe that the most important item is the 'battle dressing' because it can cover from moderate to severe injuries.
