anyone ever tried to make a mold and pour Concrete for sinkers? i know it would take a massive concrete sinker to equal the weight of a 3-4oz lead one, but i have been thinking about doing just that, making some similar in shape to "bank sinkers". i also think a "ball shaped" bank sinker would get hung up less often. a couple of the places i fish you HAVE to use a "break away" rig (3 way slip or standard rig with lighter mono on sinker leader) to fish, guaranteed to lose EVERY sinker you place out there. they are awsome spots but even if you make your own lead sinkers it can be quite costly.
