All things being equal

 Basic Facts About Frames & Strings

There are many misconceptions about racquets and strings. One of the first things people do when they get a newly restrung racquet is to see how far they can press their thumbs into the bed of the strings to see how far they can push, but a soft string bed is not necessarily bad news as the points made by USRSA Technical Advisor Steve Davis suggest.


Racquet Facts
ALL OTHER THINGS BEING EQUAL

• A heavier frame generates more power.
• A heavier frame vibrates less.
• A heavier frame has a larger sweetspot.
• A stiffer frame generates more power.
• A stiffer frame has a larger sweetspot.
• A stiffer frame transmits more of the shock load to the arm than a more flexible frame.
• A stiffer frame provides more a more uniform ball response across the entire string plane
• A larger frame generates more power.
• A larger frame is more resistant to twisting.
• A larger frame has a larger sweetspot.
• A longer frame generates more velocity and therefore more power.
  

String Facts 
ALL OTHER THINGS BEING EQUAL

• Lower string tensions generate more power (providing string movement does not occur)
• Higher string tensions generate more ball control (for experienced players)
• A longer string (or string plane area) produces more power.
• Thinner strings generates more power.
• More elastic strings generate more power. (Generally, what will produce more power will also absorb more shock load at impact.)
• Softer strings, or strings with a softer coating, tend to vibrate less.
• Thinner stirrings tent to produce more spin.
• The more elastic the string, the more tension loss the racquet after the string job.
