I have seen times a crappie dock full of fisherman, most of which can catch fish, and have one guy with one jig head/body combo that is catching fish. Everyone else tries to imitate but can't get it done. Sometimes they can be real picky. Two weeks ago me, a buddy, and his son were fishing and they were catching ten to my one, and bigger fish. Come to find out we were throwing same body shape and color, clear with blue sparkle. They had on a pink jig head and I had a chartreuse.
