STRING TENSION
THE TIGHTER YOUR STRINGS THE LESS POWER. THE LOOSER THE STRINGS THE MORE POWER. JOHNNY MAC STRUNG HIS RACQUET LOW ON THE SCALE FOR POWER. THE REASON IS HE HAD A VERY SHORT BACKSWING IN THE PRODUCTION OF HIS SHOTS. THIS ALLOWED HIM LOTS OF TIME TO DECIDE WHERE TO PLACE THE BALL AND USE THE POWER OF THE RACQUET WHEN TAKING THE BALL ON THE RISE. HE ALSO FELT THIS GAVE HIM MORE CONTROL AND FEEL WHEN HITTING THE BALL.
