If your local tackle shop doesn't have a large selection of Plano boxes, you might try Jann's Netcraft. They have a pretty good selection of Plano and other boxes your spinners should fit in. Go on-line at
www.jannsnetcraft.com or call 1-800-638-2723 and order a catalog. One of my favorite trout tactics is just a 6mm bead on the leader above the hook. It works very well dead drifted in the current, especially f there are fish spawning in the area. Beads, hooks, swivels, and split shot would all fit well in the film cans.
