The killer jig for me is a 1/64 or 1/32 0r 1/16 Bass Pro brand marabou jig with a red head chartreuse body white tail. I like marabou, it has more action than plastic. Especially in cold water. But I do have a box full of plactic skirts that I do use. Sometimes the crappie like a smaller bait like the 1/64 and I just put a slit shot about 6 to 8 inches up the line to get it down.
