I've had success fishing the Ned rig in East Texas grassy lakes, particularly at the grass edges where the lake narrows/pinches in--ex: bridge areas.
You have to have a lot of patience waiting for it to get to the bottom. If you are a power fisherman, you can try a similar technique with any 1/4oz--3/8oz skirtless ball head jig and a medium rod. If around grass, use one with a small weed guard. They do make Ned rigs with a two pronged thin metal weed guard--they are OK.
I don't know Rayburn or Toledo, but looking at maps, I'd like these areas for a ned rig at the grass edge.
