I EDC more bandaids than that in my wallet. I agree with Pika about elastic (Ace) bandages. They are extremely effective for the kinds of problems backpackers encounter. I usually pack two. Something that ought to be mentioned is the degree of improvisation you will employ for splints and other items. How many triangular bandage precursors are in the rest of your gear? What is your procedure for producing a leg splint? I am a broken record on this, but an important element is the level of training and experience within the group; indeed, it is the most important element.
