How can I use lead tape to get more "control" from my "power" racket?

Put a strip of lead tape on both sides of the frame and/or on the top and bottom of the frame. Make sure you put an equal amount of tape on each side of the racket. Also, be sure to put the same amount of tape that you put on the head of the racket on the throat area of the racket so that the balance will stay the same. Keep adding more tape untill you've found the weight you like. More weight equals more control. Don't worry about putting too much tape on, as you can remove it just as easily as you put it on.
