We won the Midwest Crappie Trail Classic on Kaw last weekend. We had 18.04lbs for a two day total. Pre fished brush on Friday and nothing for tournament fish. Caught our fish on Sarge bridge from 14-24FOW. We used 1/2 jigs with Crappie Pro Wasshoppahs. We strolled the rocks about .2mph and did a method called snap jigging. We would hit the rocks with our heavy jigs and snap them up about 1 to 2 foot. The fish would hit them mostly on the fall back down. We caught them this way on other parts of the lake in rocks. You might want to give this a try as they are feeding heavy and will not be in brush when feeding. Hope this helps.
