I've been on a nice pattern at the above-referenced lakes for the last week catching crappie. Trolling a silver & black Wally Diver about 100 ft. behind the boat at ~2 mph. I've been to Cowan twice and CC once (CC last night) and have been absolutely killing the fish. The pattern is to troll in 20-25 feet of water, and the fish are suspended about 10-12' deep. Look for schools of baitfish, and troll there. The first fish I usually catch are small, so I let out more line to get the bait deeper, and that's where the bigger fish are (12-13"). The only problem with this method at CC is once I find the bigger crappie, I start to catch the drums, also. I had a couple hits on a chartreuse Wally, but it is primarily black & silver. I have had absolutely no luck with any other crank, having tried every other shad-type crankbait I own. One more thing, if you want to go get some of these Wally Divers, Wal-Mart has them for about $3.75. However, don't go to the Wal-mart by the Dayton Mall, because I bought them all out yesterday! Good luck, I'm interested if anyone has success with this.
