unpainted jigheads, with appreciable success, I don't think there's much difference ... one way or the other.
But, I will say .. whatever gives you confidence in the bait - go for it. You will fish that bait "better", if you have confidence in it. Size, weight, body color(s), head color(s), hook color(s), black eyes, red eyes, white eyes, no eyes, or whatever ...... if it makes you feel more confident that the bait will produce, then it probably will !! Just MHO .......... cp
