It's kind of like the guys out west that throw the big swimbaits looking for that one big bite. Big worms catch big fish. At least down here. I can't comment for the rest of the country. Heck, I'm not even able to comment on northern Florida. But down here for big fish, you flip the mats, use frogs, or use big worms. Tournament records have proven that. Thats not to say that other baits don't catch big fish. The Skinny Dippers have proven otherwise. I've caught plenty of big fish on smaller worms. I've caught lots of small fish on big worms. I do believe that the larger plastic baits catch bigger fish, at least down here.

Just for me I fish a smaller fluke because I want to match the bait size.

No one would debate that logic, but realistically speaking, every time you stop the boat

the size of the baitfish may be different. The clouds of baitfish that mark on the sounder

are of various sizes, shapes and densities. In Florida for instance, you might be over

a cloud of 1½" taillight shiners in one spot, or a school of 10" golden shiners in another spot.

IMO, there is a time and a place for everything.  I through mostly senkos when I'm worm fishing.  Usually it's the 5 or 6" size,  but I also like to through the big senkos.  I think they are 7 inchers, but they are way thicker than the 5 and 6's.  I can't say that they catch bigger fish,  however sometimes they catch fish when the others aren't.  As far as fish size,  I watched a little dink take my big senko and it took him 3 full gulps to get it.  I should have jerked it away from him right away,  but it was kind of amusing.
