I think you are missing out on a more important issue. If you are letting the SB take you out of the hand on a regular basis you have a serious problem. You need to frequently (not always, but often enough to keep him scared) stand up and say no damnit, you do NOT want to mess with me like that. If you aren't willing to put all your chips behind the best starting hand there is, then when are you going to do it?

Push all your chips into the middle anytime you can get heads up with AA. Period. You won't win them all, but you will win far, far more than you lose in the long run.
