I fish out of a kayak, so my organization is kind of important. Back when I fished out of a bass boat, I took everything with me. That consisted of the old amber Plano Magnum and two other bags filled with 3500 boxes. I also had about 7 rods. All of it went on the water.
Now, I have condensed my tackle load into one milk crate that holds the old Magnum and three 3500 boxes. I have my hooks and jigs organized into pill bottles that share a top to make one long storage cylinder. Those either go in the bike bag behind the seat, or in one of the 3500s. I obviously no longer pack all the tackle I own in the boat, instead, I pack enough to get me through the day. I only have enough bullet weights, hooks, jigs, etc. to fish for one day. All of that stuff takes up room, and adds weight. I even only buy black or brown undressed jigs, and keep a bunch of different color skirts in a bag. I only take the hardbaits I think I might need with me for the day.
You start to look at lures differently fishing like this. It makes you appreciate a compact, versatile lure. Rat-L-Traps, spoons, grubs, and blades are lures that can do a lot of different things for you, and they don't take up much room. The kayak has made me a more efficient and smarter angler. The paddle helps keep you in shape, too.
I also carry a maximum of four rods with me, and they mount to a vertical rig attached to the crate, or are kept in horizontal rod holders along the sides when I'm back in the jungle (I can only take three rods like that). You can see my rig in the water in the Show Your Ride thread. I only recently put it up, so it should be on the last page still.
All the other tackle still goes to the lake, it is just stored in the truck or the camper. If I feel like I need a lure left behind badly enough to paddle a few miles back to the truck, then I'll do it. Hasn't happened yet.
