Dean, for some reason I have the impression that F1 bass are more aggressive & grow faster initially than pure Florida bass, but that their ultimate max size may not be as big. However, the current world record LMB was an intergrade, so what do I know?
F-1 LMB are more aggressive than pure Fla LMB but they do not grow faster than Fla LMB (possibly except for the first few mths). In a natural enviorn aggressiveness can be both a positive or a negative trait. Some studies show over aggressiveness can result in the recipient being eaten by larger fish. Over time I am not sure there is a difference in size actuality of Fla LMB and F-1 or Fx. The studies I have seen show that a small % of Northern genes greatly reduces the negative trait of non-catchability. I have seen no info on the breakdown of LMB genetics and ultimate growth (size) potential.
I have to always caution that this applies to 50% of the LMB population. Male Fla LMB are much smaller in comparison to their female counterparts than is the case for northern LMB. F-1 and Fx - I don't know if that holds true.
