The soft-side is a smarty move. I have been using them for about ten years. Mine holds six of the large plastice stackable boxes. I bought several extra plastic boxes. I load one with soft baits and use it year round, I have one for jigs/spoons/spinner baits that goes every trip. (I also keep lots of worms stowed in the boat, can't ever have too many.) The others I rotate according to the time of year and the type of fishing I plan to do...........................but.
Most of my fishing is either throwing a worm or jig or flipping a soft plastic into brush piles. I never leave home without at least two flipping rods. Some of the guys I fish with laugh at my rods, all I need to do is knock the guides off, put a tip on, and I'd be ready for a game of pool. You gotta have the right "stuff" to get a big ole bass out of a brush pile. Heck, sometimes, ya even have to lift the brush pile out with the fish.
