I use unpainted Jig Heads...
for the most part. I used to think jig head color was important. I fished with Terry Whaley on Weiss last February and he only used unpainted jig heads that day. Said he hasn't found it makes much difference to the crappie. We caught fish all day long on them. I use painted heads when I'm fishing jigs real slow (like under a bobber). Figure the crappie might take a closer look when the jig is moving slow. Since I pour my own it is also costs less to use unpainted heads.
