I would bet more on the turn and river. Bet $4 on the turn and the rest on the river. Based on some of your previous posts, I think you need to work on value betting bigger, so that you get paid off more. Sure when you make these small raises and a 1/4 pot bet on the river you will get called often, but I think it is far more +EV to be throwing down 2/3 - full pot bets with your monsters.
