The tip can be done in several different ways with the ball going high or low. The main difference is where you tip the ball on your stick. If you want the ball to go low the contact is higher up the stick and for a high ball the contact is lower down with the tip of the stick. When the ball is coming with speed you will use the tip because contact with higher up the stick will cause the ball to shoot over the net. When tipping backhand, the face must be kept open, with either a low or high stance.
