If I recall correctly, Bob Lusk said that the big difference between North & South was not perfect days for LMB, but rather perfect days for BG, backbone of the LMB food chain. South has more growing & spawning days for these fish, which means more of them for LMB to eat.
This would help to account for the oft-observed fact that Florida LMB are more cautious about what they put in their oversized mouths. They have more prey for longer time than bass up north, so don't have to rush or take chances like their Yankee cousins.
