put an 8/0 O'Shaughnessy in the head. wrap about 1/4 inch of thread around the middle of the hook, and put a dab of super glue on before you slide the hook into the body. the weight of the hook is generally enough. i have taken bass into the 30#'s on this set up. for some added weight, occasionally i will add nails, or you can use the lead "nails" slug-go produces.
personally, i like Ledgerunners better.
