If a Crappie can see the bait and they are hungery they will bite it. I have caught Crappie on 1/2 oz Bass Spinerbaits, Bass Crankbaits and Walleye jigs. I have gotten them on a 10 inch worm, and they all weren't big Crappie. I have used the walleye minnows and caught 4 inch Crappie on them. Just because you use a big bait doesn't mean that all the Crappie will be big, but a majority will be bigger fish. EB
