My suggestion for you is to spider rig slow with minnows, tight line [ no floats ] if you can't do that try trolling slow.
If you don't like to do that try sitting still and put poles out all around the boat, and if no bites move about 20 yards and sit again.
You can always try shallow and fish around trees or liddy pads, watch out for snakes and wasp.
Reelfoot is great crappie lake and the restaurants have very good food, you'll enjoy your trip.
Good luck..............crappie cowboy
