It depends what you like in a tennis string but I personally like babolat revenge polyester string.
The one(S) in your racquet...nut bar
There is no 'best string'. Even professionals use different strings because different strings suit different needs.
They don't always do it when the balls are changed, but players do change their rackets every couple games. Because they hit so hard, the string tension becomes looser after a couple games. Being pros, everything needs to be exact. That lesser string tension compared to the regular tension could mean one ball being an inch out, instead of being in. So yeah, that's why players change rackets.
Every tennis racquet is marked by the manufacturer with the recommended range of tensions. For example most medium sized racquets can be strung from 22Kg up to 28Kg. For maximum control the higher tensions are best. For maximum power the lower tensions are best. For a good mixture of both control and power the tension should be midway - that is 25Kg in the above example. The thickness or gauge of the string will also effect the power. A racquet tension of 25Kgs with a thin (1.20) string will produce more power than a tension of 25Kgs with a thick (1.35) string. If your average shot is falling nearer the service line than the baseline then either lower the tension 1 or 2 Kgs or use a slightly thinner string to get more shot distance. However, be warned, a thinner string is not as durable as a thicker string so it may need replacing more often. If your average shot is going off the end of the court then either increase the tension on your racquet by 1 or 2 Kgs or use a thicker string (or both) to reduce the shot distance. Developing more topspin on your shots will also bring the ball down earlier - so there are many more factors than just racquet tension and string size to consider. An oversize racquet (i.e. the head is larger) will also produce more power since the central sweet spot is larger and also the strings produce more of a trampoline effect. A heavier racquet will also produce more power but you may lose a degree of control due to the difficulty of manoeuvring the extra weight. As a generalisation a keen amateur would probably play best with a medium size racquet, a string tension of around 25Kgs, a string size of around 1.25mm, a racquet weight of around 300gm and a desire to hit topspin whenever possible. However the question "What tennis racquet tension makes you hit a ball harder?" may not be as important as "Which tennis racquet set-up will help me hit more accurately?" The last thing to mention is that the size of the grip on a tennis racquet (between 4" to 5") is crucial to hitting accurately and powerfully. Always buy a racquet with a grip that your hand can go nearly all the way round (4 1/8" or 4 1/2" for most adults). A grip that is too big will produce poor tennis and cannot be reduced. Whereas a grip that is comfortable will produce better tennis and the grip size can always be increased later if necessary.

String tension is measured in pounds (lbs). Given below is the typical classification of the string tension.Low tension: 18-20 lbsMedium tension: 21- 23 lbsHigh tension: 24- 26 lbsVery High Tension: 27 – 30 lbsFor the Nanospeed series, the tension can be set to around 25 lbs for best resultsThis answer is courtesy Sports365.in through its blog Sports365blog.com.
As you increase the tension on a new (or unstretched) string, the string will lengthen. The best way to minimise this effect is to pre-stretch the string with some pliers before attaching both ends to your guitar. Also as you alter the tension of each string this affects all the other strings around it because it changes the amount of force acting on the neck of the guitar. If you have a tremolo on your guitar that will also bend with increased tension. Tuning a musical instrument is a painstaking process as they are so finely balanced to acheive perfect intonation.
Yes it is. It is not recommended to do this all the time though, as each gauge string exerts different stress and tension on the guitar neck. It's best to do this only until you can get yourself new strings.
