We dove right into both the bags and went through the individual items and why they were worth carrying. Some specific items that were unusual were pull string fireworks and pop it's for temporary security. I also carry a drawstring backpack for expansion and goodies in the field you find.
We talked about the intended use of the bag and the size you may need. Some high end examples and inexpensive solutions.
A shortened version of the water and fire-starting co-ops were discussed with the materials I had in the bag.
Weight and size issues were weighed with specific scenarios in mind.
First aid was defined with the life or limb first then the boo boo's and headaches as a secondary concern.
Portable shelter in my case is a military poncho liner and civilian reversible poncho each vacuum packed to prevent mildew and reduce the size.

With that in mind my BOB bag has a backup to my EDC and alot of the contents go straight into my pockets if I have to carry it.
Scatterbrained I know but that's about it.
