Something I've been adding to my game, and its been working....

Call the turn and raise the river. If he re-raises the river you can safely fold. There are a bunch of advantages to this line over the one you describe, including that it allows the opponent to continue with a bluff and reduces the chance of getting re-raised either (a) on a bluff when you might fold, or (b) when you're behind but with a hand that you can't fold.
