I'll try to help you. I have never fished either lake though. Forget the jigs for now, we'll get to those later. Rig your rods with slip floats, 1/16 to 1/8 of weights and #2 to 1/0 hook. Hook your minnow thru the eye socket. When your going across the lake look at your depth finder and see at what depth most of the black dots are at. That is the depth you need to start looking for brush and drop offs. Do not worry about actually seeing fish on the depth finder since they are going to be on the bottom or tight to brush. Set your slip floats to just above the brush. If your not getting hung once in while your not going to catch fish consistantly. If the lake has docks find some that have at least 15 feet of water on the end of it and fish around them. If there are lights on the docks then there is probably brush around it. Another good place to start, if your lake has any, is around the fish attractors that NCWRC has put out. Be patient, this is a tough of time of year to fish as are those 2 lakes. It may be worth your while to drive over to High Rock where we can get you, your bro and nephew on some fish before anybody gives up on crappie fishing. I hope this helps you some.
