My Betting Idea

Oddsmaker spend more time on high profile games and leagues because they receive the most betting activity. The NBA, NFL, MLb receive much more attention and sharper lines than small conference college basketball, cfl, arena, international soccer, etc. For all the people saying NBA is fixed, players are in on the game, why even bet those sports. I have had the most success on smaller leagues, I can only profit on cfl, arena, and small college football and basketball conferences. So I will only bet on those sports and track how I do from now on. I even asked my book to remove betting options on any line that doesn't involve cfl, arena, college football, and college basketball.  So I can't lose money on sports I don't ptofit on because i won't be able to bet on them. What do you think of betting and trying to profit on low profile games, I feel if you know a lot on these teams, that the books won't because not much money comes in on those games and they won't care about them.
