Does anyone get superstitious about using one of their sportsbooks?

Everyone shops around for the best lines but, have you ever had all (or most) of your plays at one sportsbook end up losing while you are winning your plays at the others? Or, better yet, you go on a heater using a specific book and then you use it exclusively. Does these "trends" impact where you place your bets or do you stictly go with best line available?

I'm not normally superstitious but I do get curious about why these trends occur.
How about you? Do superstitions come into play on which book you use?
