The importance of a tennis string is often ( mistakenly! ) underestimated. Tennis players often spend a lot of time and money looking for the perfect new tennis racket, with all the latest technologies, and then string it with a random (and often cheap) tennis string. It is often said that you play better with a good tennis string on a bad tennis racket, than with a bad tennis string on a good tennis racket!

The importance of a tennis string is best demonstrated by the fact that a tennis string is the only material which comes into direct contact with the tennis ball! The eventual playing characteristics of a tennis racket are primarily defined by the tennis string and its qualities!
