I should also have mentioned that IF you bend over too far, that lowers the orbit of your club, since your arms and club 'are heavy.'
Imagine batting a baseball with a heavy bat. The weight of your arms and bat might well cause the swinging club to come in too low and sky the ball -- pop fly.
In golf there is a critical angle between the spine and arms, looking down the line. If the arms "reach out," all support UNDER THE UPPER ARMS is removed, leaving you at the mercy of your best efforts and gravity. But if with a short club they hang, no force to pull the club down towards your feet will occur. If with a longer club they HAVE to reach out but the chest does not rise under the upper arms, they are like the batter with the heavy bat: so the chest NEEDS TO BE TILTED TO A MORE ERECT POSITION TO PROVIDE SUPPORT UNDER THE UPPER ARMS. Then the arms and club will be PREVENTED from falling.
What this means is to experiment with a MUCH taller feeling posture with your driver so that you almost have to TOP it because your orbit is FORCED to swing higher off the ground. Once you discover how this is so important and you HAVE topped a few, THEN BACK OFF and locate the middle between too much tilt forward and too LITTLE tilt forward.
When gravity works on you to pull your arms down to the ground as it must, you prevent it not with muscular effort and struggle, but with position that takes care of the problem.
I should have mentioned this to begin with. Once you CAN hit it "thinner" then it is a simple matter to stand further or closer feet-to-ball for centered impact AND to adjust your tilt for the best depth control / low point control of your clubhead orbit.
