They are hollow. Can make them weigh as much as you like. Naked as is from top to bottom 6" - .8 oz , 4"- .4 oz, 7" -.5 oz, 6" -.4 oz. I have 5" ones too and 7" ones like the first one. Sky is the limit on sizes. With just hooks and no added weight they cast good. I have made them to the exact dim. out of wood too. I just kind of like the looks so I figured I would like them to float or suspend and that is just not going to happen with the Alum., no matter what I tried, so I figured why not wood. Just have not painted any yet. Alum. ones really work pissa cast out of a boat. Alum. ones, at least the bigger ones, will probably be a semi-rough surf condition type lure, but who knows
