I've been playing around with this lately. Just keeping it simple with a few small zip sacks. I have a Mystery Ranch medium Zoid Bag, which are pretty nice, and currently holds a first aid kit, fire starter bag (both are in your standard zip lock baggie for reference) & a Survive Knives GSO2.7. I've had a Maxpedition 4X6 pouch laying around doing nothing, so thats what I keep all the little odd ball items in. Pen, sharpie, small knife,.... I just stuff those in the Tara. And, I just got a Kifaru Ultralight Pullout for my keys and wallet, which I hang from the webbing loop in the Tara with a grimlock. Then I just stuff everything in however best fits.
