Top 5 Best Polyester Tennis Strings Reviews

The polyester-based string has been around in some form since the early 60s, but it really wasn’t until the 90s that a major shift occurred. While in the early years of its availability, many tennis players somewhat suspiciously eyed the Polyester tennis string as a poorer quality product, they slowly but surely won admittance to the hearts and rackets of professional and amateur players across the globe. Nowadays, polyesters are the strings most commonly used in professional tennis by both men and women. In fact, these strings now occupy such an important place in modern tennis, that Tennis Industry Association refers to them as “Traditional” strings.

Here are the best polyester tennis strings on the market.

The Solinco Heaven Strings Hyper-G tennis string is a newly developed, high-performance, and versatile co-polyester string designed to offer playability and control while generating extreme power and intense spin and bite. Utilizing a newly developed chemical formula in combination with the high-powered polyester monofilament fiber designed and shaped to maximize power and control while amplifying the spin and bite intensity of the ball.

Hyper-g Series

A massive spin from a square-shaped co-poly. The Hyper-G series took the world of tennis by storm when it was introduced in 2014. It produced amazing spin and incredible power, two things that were unheard of for a 100% polyester string. Soon after its release, the Hyper-G family grew to include various hybrid variations and even an all-synthetic version called X-G. One thing stayed consistent throughout the evolution of this series: massive spin potential.

High Spin Potential

The Hyper-G Heaven offers a crisp and firm precision cut with a high spin potential. This solid blend of co-polymers gives this string the responsiveness needed in a modern player’s multi-directional shot selections. The firm texture offers touch and stability, while the solid core ensures added stability and durability.

Multi-polymer Construction

The latest in string technology just arrived: the Hyper-G. This string utilizes a multi-polymer construction, combined with a new polymer extrusion process to create a high-grade polyester monofilament that provides amazing spin, feel, control, and shock absorption. This combination of technologies makes this string play like a natural gut with almost no sting – as well as being strong enough to take big cuts from aggressive players.

Shaped Polys

Many poly strings are shaped like the one above. Silver 7 Tour and Black 7 have seven sharp edges that bite into the ball upon impact and impart massive spin. These strings are both top 3 for Spin potential. Other shaped polys include Big Hitter Blue Rough and Big Hitter Silver Rough which have 8 sharp edges and then twisted. Tourna Grit is more of a textured poly that feels like sandpaper and can really grab the ball upon impact. These Tourna polys are known for their control, low power, and spin.

Round Polys

Round poly strings are smooth and un-textured. The round nature of the string helps “snap back”, which is the movement of strings upon impact. More snap-back imparts more spin on the ball. Big Hitter Deuce, as shown above, is the first multi-colored infused poly giving you the best of both worlds of power and comfort. Smooth polys also are a favorite with synthetic gut and multifilaments because they don’t wear the softer string down as quickly. Another round of Tourna polys includes Black Zone, Big Red, Big Hitter Blue, and Big Hitter Silver. All of these Tourna Polys are meant to be softer more powerful, and easier on the arm than traditional poly strings.

Soft Synthetic Strings

Multifilaments and Synthetic gut strings are the softest and most powerful tennis strings. Multifilaments are meant to mimic the elasticity, softness, and feel of the natural gut. A favorite among players with tennis elbow. They are made with thousands of fibers, twisted together, and then dipped in polyurethane to bond the fibers. Quasi Gut is extremely close to the feel of the gut and soft on the arm. Quasi Gut Armor has tiny polyester wraps to help its durability. Synthetic Gut Armor is one of the best all-around strings on the market for playability.

Buying Guide to The Best Polyester Tennis Strings

Topspin

Over the past two decades, Rafael Nadal has been a major factor in the rise in the popularity of polyester tennis strings. He’s revolutionized topspin, so it’s no wonder he threads his racquet with a complete bed of polyester.

Control

In many respects, spin and control are intertwined. It’s possible to hit the ball higher over the net with greater topspin and still have faith that it will fall back down onto the court. As a result, the increased spin gives players a better sense of control.

The string’s stiffness is the primary reason polyester tennis strings increase control for players. The ball’s stay duration is shortened due to its increased stiffness on the string bed during play.

The shorter dwell period means that players’ strings will respond more consistently. Gaming has a greater sensation of control as a result.

Players now are more strong than ever before, and their approach to the game has evolved to be more aggressive as well. With this new emphasis on control, it’s no surprise that polyester is being used increasingly frequently by players in order to attain it.

Durability

When polyester tennis strings first appeared, one of their best features was how well they could withstand breakage due to their long lifespan. Polys, as expected, have held up well throughout the years.

At the time, this was a useful tool for big hitters and string breakers. It’s possible that breaking strings will turn into an expensive habit. It can also cost you a point, a game, or a match if it occurs at an inconvenient moment.

There are a number of strings that can handle your aggressive style of play, and polys are one of them.

For our purposes here, it’s important to distinguish between the two terms “string durability” and “string tension retention.” Polyester strings have a major problem with tension maintenance, or how long a string can hold its tension.

String Movement

A lesser-known property of polyester strings is their ability to return to their original position. You might wonder, “What’s the big deal with string movement?” A great question, if it is the case.

The ability of your stringbed to produce a consistent hitting surface is directly related to your ability to manage string movement. In principle, you should be able to exert more control over your swing if your hitting surface is more uniform.

Some musicians simply can’t stand having to constantly retune their instruments. Even if you don’t think this is a benefit to you, it’s worth noting.

Comfort

Due to its rigidity, polyester strings make playing the viola a challenging experience. As long as you’re in good health and in good shape, you may not give comfort much thought at all.

If you’ve ever had tennis elbow, you know just how aggravating your pain may be while you’re playing. Thus, polys are sometimes regarded to as “harsh” compared to other string types such as the natural gut or multifilament.

The harshness of polyester strings, on the other hand, is controversial. Some believe that the harshness experienced by players is a result of the strings being strung at higher tensions. We’ll get to tension a little bit later on.

Require Good Technique

You’ll need a decent technique to get the most out of several polyester strings that are stiffer than others. In other words, your racquet must have a fast swing speed.

Among club players, though, many are hitting the ball in an unorthodox manner. If they used poly string, it would feel like hitting the ball with a table tennis bat. Club players who insist on poly should string at a low tension in order to lessen the stiffness of the string.

Poly vs. Co-Poly

Players have been baffled by the rise in popularity of the term “co-poly.” We can see that polyester tennis strings have always been monofilament strings if we go back to their history. Polyethylene terephthalate (PET), for example, is the only polymer used in their construction.

Because co-poly tennis strings are simply polyester strings with performance-enhancing chemicals added, the name co-poly makes a lot more sense.

You might expect manufacturers to experiment with co-polys in order to maintain the advantages we’ve highlighted while simultaneously resolving their downsides.

Polys and co-polys are both polyesters, so referring to co-polys as polyester strings is totally acceptable.

Frequently Asked Question

Are Polyester Tennis Strings Good?

Is using polyester tennis strings a wise idea? Players who wish to improve their spin, control, and durability should use polyester strings. Nevertheless, they’re not for everyone because of their limited power, discomfort, and the fact that they need to be re-stringed on a regular basis.

What Is The Best Material For Tennis Strings?

For tennis strings, nylon (multifilament), polyester, and natural gut are the most common materials (monofilament). Polyester strings are better for advanced players because of their stiffness and control-oriented properties, whereas natural gut and nylon strings are ideal for starting to intermediate players.

Do Pros Use Polyester Strings?

Many professional tennis players favor polyester strings, which you may have observed if you pay close attention to the sport. Professionals and advanced tennis players favor polyester strings for a variety of reasons, the most important of which is their durability and control, and spin capabilities.

Do Polyester Strings Cause Tennis Elbow?

I believe that polyester string is to blame for the vast majority of tennis-related arm injuries. More and more people are complaining of problems with their wrists, shoulders, and elbows (including tennis elbow and the more recent golfer’s elbow).

What Tension Should Polyester Strings Be?

A 48-58 lb. tension for polyester strings is ideal. While synthetic gut strings can be purchased, natural gut strings are accessible. These are the strong strings in the world, allowing you to hit the ball with a lot of speed.

Conclusion

Polyester strings are designed to be long-lasting, yet playable and responsive. While these strings are generally very effective at maintaining the tension necessary for consistent performance, a small reduction in tension over time is inevitable.

Regardless of your string preference or playing style, there are strings available to match your playing style and preferences. Experiment with different types of polys and if you’re unhappy with the results, don’t be afraid to try something new. You may just find that you’ve been limiting yourself all along.
