In golf, length does not necessarily help your game. Golf is a game of feel and touch, and hitting the ball straight. I would think that the more doped up one is in golf, the more risk there is that when you slice it, it goes even further left or right. Overall, I say dope yourself up, but it ain't gonna help you win any more tournaments if your short game (within 100 yards) stinks.

My best rounds are when I'm swinging relatively easy with good tempo, and when my short game is on.
