I've been pulling crankbaits for years. Called trolling before the fancy name. There a couple of areas on Kaw that hold crappie, lots more hold sandbass and hybrids.
Agree that Bandit baits are the best. Pumpkin seed color seems to work the best for the crappie.
White for everything else.
I like to paint blood streaks on the belly's of the white ones with fingernail polish. May be my imagination, but it seems to help
