I definitely have some "house rules" I use. I don't switch on D and I only user catch sometimes. I'm always mixing up play calling no matter what. You may just be a much better player than I am. Over the years its become apparent that if I only want to play to win, I would probably win every game, but if I want to play a good game (i.e. sim game) first and try to win second, that's possible with tough sliders.
