I understand that the extend of upper body opening in forehand is dictated by when the impact is made, which in turn is affected by the kind of grip you use. For example, with continental grip, the impact is made between your feet, so your body should stand sideways at impact; with eastern/semi-western grip, the impact is made at about where your front foot is, so your body should open up about 45-60 degrees; and with western grip, the impact is made in front of your front foot, so your body should fully open to face the net at impact - the theory goes, as I understand. How does the above rule of thumb reconcile with hitting early? I use semi-western grip and semi-open stance for FH and open up about 45-60 degrees at impact. But if I were to take the ball early, would that mean I should open up more at impact - perhaps face the net as when I would with a full western grip?
