I keep several rods with different colored jigs on them. Now talking whips? I have found that many times the color the crappie want can change on a dime. So the whip tails can and do get changed out right quick. If you were catching on motor oil and they stop biting. Change the whip not the jig. Boom they are biting again. Have caught them with natural colors in clear water and then on hot pink or chartreuse in the same clear water. Good luck and change those colors as the bite changes
