I'm with "5" on this one. I too have a soft sided Cabelas bag. Holds about 9 or 10 plano boxes. I buy the boxes in lots of 10 or 12. I fill them up, label one end of them. When I head out to target whatever, I just switch out my boxes.
For smaller jig heads, I purchase the small Stanley boxes from department stores (Harbor freight also sells them). They have removable trays. I own four of five of them so I can swap out the trays between smaller and larger ones. I have one box about 1/4 the thickness of a briefcase (same size) that holds every color of jig imaginable from 1/32, 1/16, and 1/8oz (in their own removable tray).
I have OCD "Obsessive Crappie Disorder"
