Where do you play ,that you need to be that concerned
about heat?As one of the major advantages of CC is spreading your bets,I can't see why you wouldn't do this.Perhaps you shouldn't use a 1-10 spread,but certainly flatbetting isn't your only answer.
Keep in mind that casinos have different shifts so with even three casinos to choose from,you can play twice a week and only see the same pitboss every few weeks.
