Look at Z Man TRD Ned Rig set ups. I used these a lot last year when it got hot and the bite was off for everything else I tried.

The Z Man combination I used was a light jig head with a light wire hook and about a three inch geen pumpkin senko shape but a lot tougher plastic worm. I used it with both med/lt & lt spinning rigs, 10 lb braid and a three or four foot fluro leader. It worked in shallow water or depths up to 20 feet.

There's a lot of info on the web. re this and there's other ways to fish it. Looks to me it's just a light tackle way to bass fish. No question it works. I caught bass from about 12" up to 18" on it over three or four days during mid summer. From what I've read it will work at any time and some bigger fish are also caught with this method.
