Jim Webb shared with me that in the old days most of the accoutrement kits (measure, brush, pick) that were hung off of the bag or strap were usually tucked under the flap and into the bag. That way they didn't flop around, make noise, or get torn off. They were pulled out to load, and then tucked back in. Something to think about when deciding where to hang your gear and how long to make the chains or thongs.
God Bless and best wishes, Marc
