Me too. I haven't cut or poked enough holes in myself to have a good idea of what I generally do/don't need in a self built kit. I've got a couple of general purpose first aid kits from Acklands...small one in my range bag and a larger one kept in the truck, but neither qualifies as a survival kit. Something that could be kept in a bag along with a few days of food, water, tp, and other sundries would be great.
