Just like to say that sitting out at the begining of a MTT to avoid the fish seems a bit strange to me. You should have confidence in your play and learn to take a bad beat, after all they are a big part of the game and will always happen.

In a MTT (and other games) you will always get a certain amount of players who will chase any sort of hand and your AA, KK, AKs etc will occasionally lose to these players. But in the long run, you will win hands down.

In my (humble)opinion, it is much better, and makes much more sense, to win as many chips early doors from these weak players so you have a chance later in the tourney when the blinds are higher.
