Need winners opinion: AKo preflop, adjusting to skill levels

[pal=m]

Game is 6-12, East Coast. utg. player raises. Next to act, I have AKo and reraise. The gunner and I are winning players, probably break-even with each other. The remaining 8 opponents are loose and much worse in skill level.

Question is: Knowing this, should I have considered flat-calling here instead of making it 3?

(I flopped a King and won the hand, gunner had QQ).
