i guess u are shore fishing..
i know bills bait and tackle on upper james carries small 1.5 inch tubes..
or if u are down the mountain, fishing worlds bait shop opens at 5 am..
cut a length of 3 feet off ur line, connect this to a barrel swivel, and connect to ur main line. tie the jig directly to ur line.
cast out, out to 10, jig it up 2 times and let fall counting to 5. repeat.
the crappie there are often suspended, and they will hit the tube as it falls, so dont let ur line slack, be ready for a lite strike
also, i think the bottom is pretty flat, so u could cast out, wait til the tube hits bottom and reel it in, twitching it small very slow.. this will also produce nice calico's
