I think you may have gotten away with a larger bet on the flop. As a known aggressive table they could have easily put you on a hand like AQo and figured your flop bet was a continuation bet/bluff and would call you with anything. A larger bet may have made you more money, but as you said it would have swelled the pot, and also it may have only gotten one or two callers.

With the AKo hand, do you really think it was a bad play? CBetting on the flop every time is good and bad, when you hit the board strongly, people will call you thinking it's a bluff, and will give you more sometimes on the turn, but also I've done things like hit with TPTK or held an over pair to the board and have gotten a strong reraise and had to make a tough decision. Were they just check-raising me b/c they've seen me CB a million times before, or do they have two pair or better? Besides, you may have been check raised on the flop with that hand too, maybe he was mixing up his game that hand making a loose preflop draw and got lucky.
