Not sure where the Black Crappie not hitting crankbaits thing started, but it couldn't be more wrong. I catch hundreds of black crappie by pulling crankbaits every year.

I don't fish Harris, though some lakes I fish are similar color/depth. I pull Flicker Shads a lot & do well with Slick Mouse, Flashy Pink, Chrome/Black, Red Tiger, Purple Tiger to name a few. Shad Rap in Glass Black color has also done well.

Good luck & have fun!
