We use both
I use unpainted insert jigs in most of my tubes, but I use painted heads on grub bodies. Doug likes painted most of the time. We have noticed that jigs that have a red eye/black pupil seem to out perform other eye colors when crappie fishing. I like to tie small (1/32 oz) black bucktail jigs on a chart head with a white eye/black pupil for trout and that is very effective, probably because it looks like a little fry. Mike Simpson of CrappieMagic makes a terric minnowhead jig with lifelike eyes that worked well for us on crappie this summer. - Roberta
