I've caught some big crappie on big baits while largemouth and sand bass fishing. 4 inch swimbaits, 3-4 inch flukes, 3 inch grubs... What's your favorite big baits specific to crappie? Only crappie jig I know of that is 3 inches or bigger is the Bobby Garland Slay'R.
Ive had good luck on YUM WOOLEY BEAVERTAILS.
They have a pumpkinseed/chartruese. a black/ pink and plenty other. the end of the tail is like a beaver, you can split it too, for more fluttering. if the body is a little long you can cut the top some and make a shorter profile.
You can often find them in the bargain box at wallmart. (the one on the bottom shelf of the main fishing racks).
