all kidding aside guys I really don't use anything when I'm fishing with my plastics except maybe a crappie nibble if they get finicky about biting can't tell you how many hundreds of crappie that I have caught in my life without using anything in the way of some type of bait. . One maybe you never heard of out south here we used to use WD-40 and spray are spinning glows when we were fishing for salmon licorice oil I call it is very common that use it on anything and everything when it comes to fishing out West. there is one deadly thing you can do to catch crappie take a piece of their meat and put it on your jig they cannot resist it. years ago before we had any money to buy any jigs we used to catch one crappie and make cut bait strips and hang on a single hook underneath a float it is probably one of the deadliest combination there is yet.
