I would disagree on 2 points: 1) I don't think this flop hits our opponents range harder than ours. I am much more likely to 3bet AQ-AJ then to call a 3bet with it. In position I am expecting a villain to call many more PP's and SC's than hands with an Ace.
2) I don't think cbetting this flop is unprofitable in a vacuum and certainly not when you add in metagame for getting action on later A high or K high flops.
