To get the best out of your racquet you'll have to do a little more than just use the best string.
The choice of the right tension is about as important as the choice of the racquet frame.

As a general rule: the harder you string the less power you get and the more control you have.
With lower tension you gain more power but also lose control.

In any case you should try different tensions; if you play better - great, and if you don't, you can get back to the old tension the next time.

To show you the effects different string tensions and diameters can have on your racquet's performance I created following tables:

Power Control Durability Feel Comfort
Tension
Softer more less more more more
Tighter less more less less less

Power Control Durability Feel Comfort
Gauge
Thinner more less less more more
Thicker less more more less less

To increase the durability of your strings you should not expose your racquet to extreme heat, cold or humidity.

Therefore you should always keep your racquet in its bag. To protect your racquet head you can use a head tape.

This is useful if playing on clay court or if the strings are not protected enough by the racquet head guard.

Strings lose elasticity with time, one type of string faster, and another type of string slower. This has a negative effect on the playability; players with a sensitive arm will feel it soon. In general you shouldn't play a string longer than 2 to 3 months. Then it's about time to cut out the strings and restring your racquet.
