Is it proper to hit both your forehands and backhands using the same side (face) of your racquet? Meaning that instead of using both sides of the stringbed, one side for forehands and the other side for backhands, you instead rotate your wrist, thereby the racquet, 180 degrees so that the top edge of your racquet that is perpendicular to the ground in now the bottom edge, and use the same side of the racquet for both your forehands and backhands without ever changing your grip. Is that the proper way to play tennis or is it the wrong way? Does anyone even teach people to play this way? How come no good players (6.0+) play this way?
