Q & A's
Do I need to restring my racket?
If your string has broken or frayed then thats an easy yes. But also if your string has lost tension. A loss of tension and the strings will start to behave differently. The loss of tension will reduce the amount of power and control that you can generate which will obviously affect the performance of your racket. You will find yourself trying to hit the ball harder but without any gain. And when you do make good contact with the ball the contact won't be as solid. String has an unfortunate property beginning from the very second it is put onto the racket, it loses tension. When a racket is strung it will start to lose tension straight away and will continue to decline with every hit.
How often should I have my racket restrung?
Touring professional players restring their rackets after every game because having fresh strings enhances their game. For many players, including myself, this would be fantastic but the cost would be astronomical!!!! The general rule that is accepted by the majority of professional stringers is that however many times you play in a week is the amount of times you need to restring in a year. For example. If you play 3 times a week you will need to restring every 4 months, 4 times a week every 3 months and so on.
What types of string are there?
A good all-around string category. This is the basic and most popular string choice. It also happens to be one of the cheapest. It has a crisper feel compared with Multifilaments but not as gentle on the arm as Multi or Gut. It's reasonably durable and holds tension well. A good category of string when you're looking for power and control.
Polyester & Kevlar
This is the durability category; the choice for hard hitters, string breakers, and people without arm problems. Expect harsher hits (very harsh with Kevlar) with above average control. Kevlar (aramid fiber) is extremely durable and holds tension very good, but I would never recommend it as the only string in your racquet - hybrid use only. Poly has much more playability, it's use is not limited to hybrid applications like Kevlar, and Poly holds tension fair. A good category of string when you're looking for maximum durability and control.
The top category after natural gut. Best overall playability, gentle on the arm, but punishing to your opponent. The fraying (as they wear) may annoy some. Holds tension fair. Second most expensive string after gut. A good category of string when you're looking for arm friendly, power and control.
Gut strings made from cows gut in a complex process. Because of this, gut is the most expensive string on the market. Gut strings are very popular among professional players because of its elasticity, tension stability and liveliness. Because of the high price, gut is not recommended for beginners. Gut is also very sensitive to moisture and not very hard wearing.
