I've used them in the Harpeth. I typically use a 2" or 3" PowerBait, in either pumpkin seed or that clear yellow with metal flake in low light. Of course the fish are smaller there too, so maybe go up in size elsewhere?

They really like this color it seems:




And I use the yellow one with shiny flakes in it at low light, just after dusk. It seems to pay off in clear water at that time of evening.
