Our Picks: Best Tennis Strings for String Breakers reviews

1. ASHAWAY Kevlar 1.30/16g: A Specialty Durability Option

This ASHAWAY string is a 1.30 mm, 16-gauge Kevlar reel. Kevlar is a specialty string material often considered by players who put durability ahead of a soft, easygoing feel. The product information identifies a 360-foot reel, which can be useful if you restring often or want string on hand for multiple rackets.

Durability does not make every Kevlar setup right for every arm or playing style. A firm-feeling string can be demanding, especially if you have a history of arm discomfort. If you are interested in this option, ask a stringer about a hybrid setup that pairs it with a softer string, and discuss an appropriate tension for your racket and comfort level.

The supplied product details are limited, so check the listing carefully for current item specifications and availability before ordering. Compared with the polyester options here, this is the more specialized choice; it makes the most sense when you are deliberately seeking Kevlar rather than simply wanting a thicker polyester string.

Pros:

• Thick 1.30 mm, 16-gauge construction
• Kevlar material for players prioritizing string life
• 360-foot reel format

Cons:

• Specialty string may not suit players who prefer a softer feel
• Product details provided for this listing are limited

Verdict: Consider this ASHAWAY reel if you specifically want a thick Kevlar string and are prepared to check the setup with a knowledgeable stringer.

2. Tourna Premium Poly: A Heavy-Topspin Reel in 16 Gauge

Tourna Premium Poly is a 16-gauge polyester string sold in a 660-foot reel. Its product description targets heavy topspin play and emphasizes durability and control. That combination makes it a practical option to consider if you take big cuts at the ball and go through strings quickly.

The larger reel format can make sense for players who restring often, provided they have access to a stringing machine or a stringer willing to work with reel stock. The optic yellow color is also easy to spot against many court backgrounds. Keep in mind that polyester can feel firm compared with softer string types, so string choice and tension should reflect your comfort needs as well as your breakage rate.

Unlike the Kevlar choice, this is a straightforward polyester option with a clearly stated reel length. It may be a better starting point for a frequent breaker who wants a durable string for spin-heavy play without moving to a specialty material.

Pros:

• 16-gauge polyester construction
• 660-foot reel suits frequent restringing
• Designed for heavy topspin, control, and durability
• Bright optic yellow color

Cons:

• A large reel is less convenient if you only restring occasionally
• Polyester may feel firm for players who favor comfort above control

Verdict: Choose Tourna Premium Poly if you want a full reel of 16-gauge polyester for frequent, spin-focused restringing.

3. Kirschbaum Super Smash 1.28: A Thicker Polyester in Orange

Kirschbaum Super Smash is a polyester string listed at 1.28 mm, or 16 gauge, in orange. That thickness places it among the sturdier-gauge choices in this group, while the polyester construction may appeal to players looking for a more controlled response than they get from softer, more elastic string types.

The orange color gives the string a distinct look in the racket, but color is a matter of preference and does not tell you how a setup will feel. For string breakers, the useful detail is the 1.28 mm gauge: it offers a thicker option than the 1.25 mm Tourna Big Hitter Silver. Actual string life will still depend on how you hit, your racket, and your playing conditions.

This product is a reasonable middle ground if you want a thick polyester string but do not need the long reel format of Tourna Premium Poly. The supplied specifications do not provide a reel length, so check the listing for the exact package format before you buy.

Pros:

• 1.28 mm, 16-gauge polyester construction
• Thicker option than the 1.25 mm string in this lineup
• Orange color for a distinctive racket appearance

Cons:

• Package format is not specified in the supplied details
• May not suit players seeking a soft, comfort-first string

Verdict: Super Smash is worth considering if you want a thicker polyester option and prefer its orange color, but confirm the package details before ordering.

4. Tourna Big Hitter Silver: A Thinner Co-Poly for Spin

Tourna Big Hitter Silver is a co-poly string in 17 gauge, listed as 1.25 mm. Its product information describes it as a control-oriented choice for powerful hitters and string breakers, with an emphasis on spin and resistance to string movement. It is the thinnest string in this selection, so it is not the obvious pick if your only goal is to maximize gauge-based durability.

The design may appeal if you want a string that can move and snap back as you play, while keeping a more controlled response. That is a different priority from choosing a thick string simply to extend string life. If you break strings quickly, weigh the spin-focused design against the fact that this is a thinner gauge than the 16-gauge choices here.

The listing describes the string as made in Germany. Product availability can change, so check the current listing and package details before buying. Compared with Tourna Premium Poly, Big Hitter Silver is a thinner, more spin-focused option rather than a long 660-foot reel of 16-gauge string.

Pros:

• Co-poly construction in a stated 1.25 mm gauge
• Designed for powerful hitters and string breakers
• Product description emphasizes spin and reduced string movement
• Made in Germany, according to the supplied information

Cons:

• Thinner than the 16-gauge options, which may not be ideal for maximum string life
• May feel too firm for players who prioritize comfort

Verdict: Pick Big Hitter Silver if you value spin and control more than choosing the thickest gauge available.

5. Kirschbaum MAX Power Rough: Textured 16-Gauge String for Spin

Kirschbaum MAX Power Rough is listed as a 1.30 mm, 16-gauge string with a textured surface and a silver-grey color. The product description connects that roughened surface with ball grip and spin, and positions the string for aggressive baseline play. Its thick gauge makes it a logical option to compare with other durability-focused strings.

Texture and gauge serve different purposes: the thicker size is the clearest detail for string breakers, while the rough surface is intended to support spin. The description also points to speed, so this string may interest players who want an attacking setup rather than a comfort-first one. Those are design aims, not guarantees of performance for every racket or player.

The product title identifies this as a reel, but the supplied details do not state its length. Confirm the reel size and exact package before ordering. Compared with the Tourna Big Hitter Silver, MAX Power Rough offers a thicker 1.30 mm gauge; compared with Tourna Premium Poly, it emphasizes a textured surface and does not specify a reel length in the provided information.

Pros:

• Thick 1.30 mm, 16-gauge string
• Textured surface is designed to help with ball grip and spin
• Silver-grey color
• Product description targets aggressive baseline play

Cons:

• Reel length is not stated in the supplied details
• May not be the best match for players seeking a soft, comfort-focused setup

Verdict: MAX Power Rough is a strong option to investigate if you want a thick, textured string for an aggressive game, but verify the reel size first.

How to Choose Tennis Strings if You Break Strings Often

Consider string type and comfort

Polyester and co-poly strings are common choices for players who hit with heavy spin and want control. Kevlar is another specialty option for players focused on durability, but its feel may not suit everyone. No string material is automatically right for every player. If you have arm discomfort or are unsure what you can comfortably use, talk with a qualified stringer before switching to a firmer setup.

Compare gauge, not just the product name

Gauge gives you a useful starting point when comparing strings. In this group, the 1.30 mm and 1.28 mm options are thicker than the 1.25 mm Tourna Big Hitter Silver. A thicker string can be a sensible choice for someone who breaks strings often, but it may change the way your racket feels and plays. Treat gauge as one factor, not a promise that a string will last a set amount of time.

Match the string to your playing style

Think about how you create pace and spin. If you swing fast and use heavy topspin, a control-focused polyester may fit your game. If you mainly want to reduce how often you restring, start by comparing thicker gauges and durable string types. If spin and string movement matter more to you, the Big Hitter Silver or MAX Power Rough may be worth a closer look based on their stated design features.

Choose a suitable tension with your stringer

String tension changes the way a racket feels and responds. There is no single tension that works for every racket, arm, or playing style, so avoid copying a number without considering your own setup. When switching to a different string material or gauge, ask your stringer whether your usual tension still makes sense and whether a hybrid arrangement is appropriate.

Decide whether a reel makes sense

A reel can be useful if you restring often, want the same string for several rackets, or already have a reliable stringing arrangement. Tourna Premium Poly is listed as a 660-foot reel, and the ASHAWAY product is listed as a 360-foot reel. The MAX Power Rough title identifies a reel, but its length is not stated in the supplied details. Confirm the exact package size before buying so you know what you are getting.

Check the exact listing and your racket setup

Product names, package formats, and availability can vary by listing. Confirm the gauge, material, reel length, and color on the current product page. Also consider your racket’s string pattern, the strings you currently use, and how often you break them. If you are changing several parts of your setup at once, it can be harder to tell which change made the difference.

Frequently Asked Questions

What type of tennis string is best for string breakers?

There is no single best type for everyone. Players often compare thicker polyester strings and specialty options such as Kevlar, while also considering comfort and playing style. A stringer can help you choose a setup that balances durability with feel.

Does a thicker tennis string always last longer?

A thicker gauge can be a useful starting point when durability is a priority, but it does not guarantee longer string life. Your swing, racket, string pattern, tension, and playing conditions also affect how quickly strings break.

Is polyester a good choice if I break strings often?

Polyester can suit players who hit with heavy topspin and want a controlled response. It may feel firm, though, so consider comfort and ask a stringer about tension if you are moving to polyester for the first time.

Which string in this list is the thickest?

The ASHAWAY Kevlar and Kirschbaum MAX Power Rough are listed at 1.30 mm. The Kirschbaum Super Smash is listed at 1.28 mm, while Tourna Big Hitter Silver is listed at 1.25 mm. Tourna Premium Poly is identified as 16 gauge, but its millimeter measurement is not provided in the supplied details.

Should I buy a reel or a single set?

A reel is often more practical if you restring regularly and expect to use the same string over time. If you are trying a new material or gauge, confirm the package format and consider starting with a smaller amount if one is offered.

Can I use a durable string in a hybrid setup?

A stringer can advise whether a hybrid setup is suitable for your racket and playing style. Pairing different strings can change the feel and response, so discuss both string choice and tension rather than assuming a combination will suit you.

Final Recommendation

For a frequent string breaker who wants a clearly specified large reel of polyester, Tourna Premium Poly is the most straightforward choice in this group. If you prefer a thicker 1.30 mm string with a textured surface, consider Kirschbaum MAX Power Rough after confirming its reel size. Players drawn to Kevlar should look closely at the ASHAWAY option, but its specialty material and limited supplied details make advice from a stringer especially useful. Choose based on your comfort, playing style, and package needs—not durability alone.
