In this video Phil teaches us how to use a good ball position when using irons and woods. He starts by saying you are going to want to the ball to be in different positions with different clubs because its going to make a difference. Starting with an iron it is important that you strike at a lower arc or descending hit. Its important that you're not too far forward because it will make it more difficult to hit the ball. Now when you're using a driver its different because the ball is up on a tee and is higher. Now you're going to want your ball to be on a higher stance so that you can hit the ball further and create an ascending blow to the ball.
