I'm a bank fisherman and I like to go as light as possible. LIke the OP, I store all my tackle in Plano 3700's, but when I go out, I pick what I need (a few shakey head jigs, the hooks I need, weights, etc.) and move them into smaller boxes that I can stuff in my pockets or a North Face Roo fanny pack. The following boxes are great for this:
Flambeau 00220 Small Spinnerbait Box - Designed for 6 but can actually hold 9 as well as 1/8 oz cavitron buzzbaits.
Plano 3414 Micro - double sided and lots of mini compartments. I have 3 of these. 1 for assorted weights, 1 for all my hooks. 1 side has 3 large compartments that can each fit a pack of 5/0 weighted EWG hooks. The other side has a bunch of tiny compartments perfect for mosquito hooks, drop shot hooks, beads, swivels, snaps, etc. You can take a razor blade to cut out compartments.
Plano 344985 Five Compartment - has 5 long compartments. Each compartment can hold 3-4 jigs or 2-3 crankbaits.
As for plastics I like to keep it in the original bags.
I highly recommend you guys keep a small journal of what you actually use and the quantity. I rarely use more than 3-4 hooks, and 3-4 different types of hooks in any one outing.
