My version of the truth.
Occasionally one jig will out fish all others, but, not often enough to really matter much.
It's the jigger not the jig most of the time. I like some plastics better than others because of the size, shape or toughness, not usually the color.
When fishing I start with whatever jig I finished with last trip and change when I get hung and lose it or it wears out too much to stay on the hook.
While I truly believe this I still buy new jigs and have drawers full of stuff I will never use up. But they sure are pretty.
