Some of these other guys are a lot more qualified to give you a professional opinion. I can only say what I've found in my own game. I keep my eyes on the ball until my follow through forces my head to turn. The biggest thing I struggled with in the past was looking, taking my eyes off the ball and causing some terrible shots. The biggest thing IMO is keeping your eyes on the ball through impact and resist the urge to turn your head and admire your shot at least until your follow through is complete. I don't know about keeping your head behind the ball. With the way I set up, my head seems to be almost even with the ball. I started using a strong grip, putting my hands slightly forward and teeing the ball closer to the center of my stance. This seems to have put me in the position to get that perfect little draw that I've been looking for for the past couple of years. This is just what works for me and I can't explain the technical side of it, but I know some of the other members will get you up to speed on that. I'll just sit back and read what they have to say. Maybe they'll even explain the technical side of what I'm doing and why it works.
