If you are not raising the flop so that you can raise the turn I'd go ahead and do it. In this case however I'd rather raise the flop because the pot isn't so big that you can't put pressure on draws and because if that spade comes on the turn and the passive guy bets you are not going to know what to do. He could easily have a J here and now you don't want to raise fearing a flush which means you missed out on the value of the flop raise.
