I was just talking about making myself a new FAK last week! GOYAAH went to a WFA class last year or the year before and he got some decent info from the instructor, here's what was sent along to me from him, hope it helps you as much as it helped me!
"I have three different first aid kits that I carry based on the situation:
1.The kit I carry all of the time, regardless of the situation, is my personal first aid kit. It is deliberately compact and light. This kit is a conglomeration of items that work for me and is not directly commercially available so I have attached an inventory sheet for this kit.
2.When I am responding to a mission and will potentially treat a patient in the field I supplement my personal first aid kit with an additional kit that contains some additional items appropriate for an EMT to provide basic life support. This inventory is also attached.
3.The kit that I carry for guiding large groups (1-12 people for up to two weeks) is the Adventure Medical Kit, Guide 1. It's a little pricey but it is a good kit. You can find it here, http://www.adventuremedicalkits.com/pro ... product=93
Personal First Aid Kit
This is the kit I carry all the time to provide for my personal first aid needs on a day hike or a week-long backpack. There are enough supplies to treat a couple of people hiking with you or an unexpected emergency response but this kit is not sufficient for an expedition or group outing and does not provide all of the EMT-level equipment and has no Advanced Life Support drugs/equipment).
It is important to limit your personal first aid kit to the critical essentials so it will be light and compact and you will not be reluctant to carry it all the time.
This kit weighs 490 gms (1.1 lbs) and is approximately (3”x 5” x 7”).

Emergency Water Purification & wound irrigation

a good quality pocket knife is a valuable supplemental tool that has many uses including first aid
At the expedition level/Group Guiding level, I have had very good luck with the Adventure Medical Kits. I use the Guide 1 kit with only a few supplements (e.g. SAM splint) which is adequate to care for about a dozen people in a wilderness setting."
