I do believe the Florida bass fight harder. But that doesn't mean much since I've never had one, even a 10lb fish pull more than maybe 20 feet of line off the reel. So I don't think bass are particularly strong fighters. But they make up for it in other ways. If you want something that pulls back hard, go catch a blue cat.
Just my .02
Well..I have to sort-of correct myself here.. I caught this bass over the weekend in a creek west of Ft. Lauderdale. And while I didn't lend much credence to the LMB in terms of it's fighting qualities, I have to say this particular fish proved me WAY WRONG! I hooked him on a worm, in the corner of the mouth on an ancient, beat-up spinning outfit my dad has sitting on the back porch. And I tell you as soon as I set up that fish ripped drag hard! Then he came up and jumped at least 3 feet out of the water and repeated that jump again. And then pulled more drag! Dang thing thought he was a smallie or something.
About two casts later I caught its twin brother and it came up shook it's head and gave up, hooked the same way in the corner of the jaw. Go figure. For an instant I thought it might have been the same fish. Even had to inspect it for a hook mark to make sure. But it was definately a different one.
