String Facts
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.
Decreased string density (fewer strings) generates more power.
Thinner string 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 strings tend to produce more spin.
Increased string density (more strings) generates more control.
The more elastic the string, the more tension loss in the racquet after the string job.**
* Although Wilson’s research for their Sweetspot string disputes this statement.
**Pre-stretching aligns (stretches) the polymer chains in the string and “sets” the string, which reduces tension loss, albeit slightly. Generally, the more pre-stretching (prior to stringing) the less tension loss after stringing.
