Raise more preflop.
Cbet size relative to pot is OK. If they chase, they're gonna pay. If you take it down on the flop, it's OK. The more cards you see with aces, the more likely it is that you'll be beaten.
My philosophy: winning a small pot beats losing a big one (I've had more than a few times where all I've picked up with aces were the blinds. It happens.).
