You can try using shad to catch them.But if they are eating topwater you should take advantage. Topwater is some of the best fishing out there. A say try a popper or jitterbug. You could even try a buzzbait or spinnerbait across the top of the water.I think you should try a floating rapala first though.Probably a number 9 or 11 depending on how big the fish are your trying to catch.Try some of these and tell me if they work.
