How to choose your tennis racket string?

The materials used are polyester or polyether or a mixture of different materials (co-polyester). The advantage of monofilament tennis strings is their increased resistance, better ball control and better spin generation. There are more and more "soft" monofilaments on the market to give the tennis string more comfort and playability. The latest developments are structured strings (strings with multiple faces: pentagonal, hexagonal, etc.) to give more spin to the ball. Monofilaments can also be used in a hybrid setup on the mains with a multifilament string in the crosses to provide a good compromise between durability/resistance and playability. Warning: monofilaments transfer more vibrations and shock to the racket than a multifilament. If you experience forearm pain, we advise you to switch to synthetic/multifilament or gut tennis strings.

Multifilament tennis strings do not have a central core, but are composed of hundreds or thousands of filaments braided together and wrapped in a protective layer (sheathing). Multifilament tennis strings will tend to fray with wear. Multifilaments are the closest strings to natural gut and offer excellent comfort for players suffering from muscle pain (tennis elbow, etc.). They offer great playability, good ball speed and absorb vibrations very well. The main disadvantage is their tendency to break more quickly than a string with a central core. We advise you to pre-stretch the string to improve the lifespan of the tennis string and reduce tension loss. Multifilaments often tend to be more expensive, but are a cheap alternative to natural gut.

The construction of this tennis string features a monofilament central core with a layer of twisted filaments around this central core. This string construction is used for an economical use of a lot of nylon. The central core provides resistance to the tennis string while the layer of filaments gives more playability than a classic monofilament.

Hybrids consist of having two different tennis strings on the mains and crosses. The common use of a hybrid is to put monofilament in the mains and multifilament or gut in the crosses. The string placed in the mains will dominate the hybrid setup and generally provide control, spin, and durability. The cross string will offer more playability, comfort, and power. The exception is Roger Federer, who uses gut in the mains and monofilament in the crosses. This combination will not last long for heavy topspin players. The use of hybrids is a good alternative for young players (over 13 years old) who break strings frequently. The lifespan of their tennis string will be increased. However, we advise stringing at very low tension to prevent forearm pain in the young player.

Before the arrival of nylons and multifilaments, gut was the only tennis string available. Today, no string achieves better playability, power, comfort, and feel, although multifilaments come close. Gut remains the tennis string that offers the best performance! The price for natural gut is prohibitive for many, and although they tend to have a waterproof coating these days, bad weather conditions reduce the lifespan of gut.

Textured tennis strings are designed to give more spin to the ball. These strings tend to have a monofilament central core with a uniform filament top layer. Another layer of thin monofilament is added in a spiral shape around the string to enhance spin generation.
