You only want to take down blinds with AA? I'm willing to risk a bit more than that, and I want callers. If you don't want to see a flop with aces, what hand do you want to see a flop with. Don't let them see a cheap flop, I agree, but what's the point of taking down just a couple of bucks with the best hand at the time.

As has been said, aces will hold up 80ish% of the time heads up. So you need to maximise the winnings on the 80% to make up for the losses of the 20%.
