I've stored them a million different ways and none of them seem to work long term. Currently using this ^^ but jury is still out on whether I like it or not. Great concept but doesn't fit into my storage box on the boat neatly..(odd shaped compared to my Plano boxes and is currently in another compartment)
I've most recently taken to just carrying a few baits and a box filled with skirts, blades and assorted parts. This way I can change a bait to what I want in a few minutes and don't have but a handful of actual spinnerbaits in the boat.
