Good line?

[gol4pro]

7 handed 50 NL, stacks somewhere around 60$. I have a LAG image for some reason (although I'm 17/9/4!), so I'm not crazy about playing a big pot OOP with TP 3rd kicker.

I min raise to 1$ UTG with A [img]/images/graemlins/diamond.gif[/img]J [img]/images/graemlins/heart.gif[/img], UTG+1 calls (moderate loose passive), SB calls, BB calls

pot 4$
flop A [img]/images/graemlins/spade.gif[/img]3 [img]/images/graemlins/spade.gif[/img]5 [img]/images/graemlins/diamond.gif[/img]
-- I bet 3$, UTG+1 calls

Pot 9.5$
-- turn 5 [img]/images/graemlins/club.gif[/img]
-- I check, he bets 3$, I call

River 6 [img]/images/graemlins/heart.gif[/img]
-- I check, he bets 4$, I call

On the turn... I could really only put him on Ax, a set, or a flush draw. He wouldn't bet a flush draw there, but he might also fold a really weak Ace, so I decided to let him bet it. He could also have AK/AQ-- which he would bet like 1/4 the pot with and save me money when he has these.

I almost donked the river, but thought he might get away from A8 or less.

Is this too passive?
