Ten basic tips to remember when buying a new racquet.

1. A heavier frame generates more power.

2. A heavier frame vibrates less.

3. A heavier frame has a larger sweetspot.

4. A stiffer frame generates more power.

5. A stiffer frame has a larger sweetspot.

6. A stiffer frame transmits more of the shock load to the arm than a more flexible frame.

7. A stiffer frame provides a more uniform ball response across the entire string plane.

8. A larger frame generates more power.

9. A larger frame is more resistant to twisting.

10. A larger frame has a larger sweetspot.

This list is only designed as a general guide. While a stiffer frame generates more power, a stiff frame badly strung may generate less power than a more flexible frame properly strung for power players. While a heavier frame generates more power, it can also decrease maneuverability.
