hi Max
it is not possible to compress the ball between the ground and the club face due to the loft of the clubs. if you take a 7 iron and put it behind the ball on a table you will see the the face meets the ball about half way below the middle on the ball and you will see the the shaft of the club leans forward a good bit too.
this compressing of the ball between the club face and ground is often talked about but it is not possible to do even with the shaft almost horizontal with the ground. the only compression you get is off the face. it's the same when people talk about hitting down on the ball to do that you have to hit the top half of the ball and you cant do that even with say a 1 iron you still hit just below the equator or middle of the ball. the degree of loft on a club does not let you hit below the middle of a ball.
get a club and put it next to a ball and you will see just what i mean.
cheers
bill
