A flasher is a definite need since Crappies tend to suspend in deep water during mid winter.
Fishing at peak bite times, early morning first light, late afternoon, cloudy days, and at night. All lakes differ in what time is best. Lakes with a lot of pressure and clear water are usually better at night.
Tip Downs are one of my favorite ways to catch Crappies, especially at night. If you want more info on them message me and I can help you out.
For jigs I like little cecil, ratso, slender spoons.
