Re: First Aid kits...STOMP or ???
I did pretty much the same thing Ratbert did by breaking down my IFAK needs into two categories and splitting them up. My small first aid kit has assorted bandaids, Neosporin, Mini-Leatherman, Motrin, Immodium, and Benadryl, as well as some regular gauze bandages and tape. The trauma kit has one TacMed Solutions Olaes bandage, 4" Kerlix, Ab Pad, Tourniquet, Duct Tape, ACE wrap, two pairs of Nitrile gloves, Chemlite, and a CPR Mask. The Olaes bandage is pretty cool in that it is several things rolled into one and came highly recommended.

My trauma kit fits into a 100rd SAW pouch and goes everywhere my Eberlestock does, while the small first aid kit goes in the top pocket.
In my vehicle I carry similar items just a few more of each really like two tourniquets, two Olaes bandages, more Kerlix, more assorted bandaids..that kind of thing.
If you are going to put one together yourself check out Tac Med Solutions and Rescue Essentials, they were really good to deal with. The rest of the stuff came from Walgreens.
