You have to love rooster tails for just about anything. Early spring trout fishing when the streams are still cold and when everyone else is working red wigglers slowly on the bottom, try a #2 or #3 black rooster tail with a worm on the hook. When trolling for crappie I put out one line with a small yellow rooster tail. Some days it doesn't matter what you use, and most days a 1/16 oz jig with a kalins tail outfishes all else, but on those days when nothing is biting the rooster tail will put a few in the box. No matter what I'm fishing for I never go home empty handed until I try a rooster tail.
