NL10 Multiway AA pot line?

I didn't have any reads on this player. Later after he left I still had no reads. I felt checking the flop was better as the only thing that I might have gotten to fold was AK which was beating me by the turn. The other player which I was more worried about in the hand was the other caller who was running at 5/3 over 300 hands. I felt by betting here I would just be adding more money to the pot that I would have had to fold on the turn to a nasty bet or shove.

Was this line bad? Other than looking weak
