You'll have a bigger sweet spot and a more powerful shot. Large head frames are great on volleys. The stiffer the racket, the more energy is returned to the ball. When the ball makes contact with your racket, it stays there only a short time. Any flex in a racket is wasted energy - power that cannot be transferred to the ball.
Stiffer rackets generate more power.
With the trend towards stiffer frames, it is essential to find ways to reduce shock and vibrations. If all three accessories are simultaneously used, vibration dampening is increased by over 70 percent and shock absorption is increased by almost 60 percent. With today's rackets getting lighter and lighter, it has become more important that the mass, or weight, is retained in the head. A super lightweight racket with mass in the head provides great maneuverability with the added benefits of superior stability and enhanced power return. A lightweight racket with minimal mass in the head can provide great maneuverability, but could cause twisting upon impact, resulting in less stability and less power.
