Is this line really that bad verus a bad/calling station?

[Salerosa]

600 NL 6-max

Villain in this hand appears to be pretty bad, he bought in for 600, I watched him lose it down to about 280 calling down with mid-pairs and top-pair weak kicker, he just recently doubled up with some obscure hand to get back to around 560. I have about 750. On to the hand...

One limper to me I make it 30 to go with AKo on the button. BB (villain) calls, limper folds.

Flop70) comes A Q 6 rainbow

He checks, I bet 75, he calls.

Turn(220): K putting out two of a suit

He checks, I bet 150, he minraises, I put him in for his last few bucks.

How do you like this line verus the type of opponent I just described?

How about verus a good opponent? Check turn, call river unless I fill up, throw out a 1/3 pot value bet if he checks to me on the river?
