this method can prove to be effective, however i believe that its effectiveness is limited to the very active fish. the active fish will hit whatever and the larger baits provide a more stimulating target. i personally prefer using smaller rigs because i feel you get a higher strike rate. your 'average' size may be smaller than with large baits, but that is because of the higher quantity of fish. my largest fish have come on the smallest baits.

there really is no magic formula. it comes down to having a lure in the right place at the right time. sometimes this comes from using smaller baits worked slowly over a certain area and sometime it comes from burning lots of water with larger baits, its a lot about luck.
