Oh, and another thing. By playing your early big stack super tight you create the table image of yourself as tight/solid. So, when you start pushing things around once the blinds get bigger the inexperienced 11s type players don't know how to handle you. You'll have already stolen 3 or more sets of blinds before they catch on to the fact you are pushing everyone around.

So, by loosening up with your bigger stack early you fritter away both the power of the stack once the blinds get bigger and the power of your tight/solid image.
