Tiger bass,F1's and Northern.

I have a question. Whats the deal with Tiger or F1 bass. They are a mix between the Florida and Northern but wouln't gen 2 or 3 of these revert back to there dominant gene like (go back to a Florida or a Northern. Also what is everyone's experience with Florida some say when they get larger they will not bite. Also with Northern b ass what are peoples experience with them? Thanks
