Tennisnerd and ReString Play With Zero in Spain

When ReString co-founder Juan drove from Madrid to Marbella to meet Jonas from Tennisnerd, he wasn't just delivering string samples.

Jonas has spent years building one of tennis's most trusted review platforms, where thousands of players turn for unbiased equipment analysis.

His testing methodology combines real match play with technical evaluation, making his assessments particularly valuable for players choosing strings.

During their first meeting, Jonas put Zero through rigorous testing on the clay courts of Marbella with Juan.

What started as a product review evolved into an ongoing friendship, with the two regularly exchanging insights about string technology and performance.

In this article, we'll explore exactly how Jonas tested Zero and what his thoughts are about the string's performance across multiple racket setups.

How Tennisnerd Reviewed Zero

First, Jonas tested the 17g (1.23mm) gauge in his 2022 Head Extreme MP at 53lbs. Then the 16g (1.28mm) gauge in his Babolat Pure Aero Rafa 2023, also at 53lbs.

The two-hour hitting session with Juan on clay gave Jonas plenty of time to feel out the string's characteristics. But he didn't stop there.

Over the following days, he took Zero back to the courts with another playing partner and with more rackets to get an even better understanding of the string.

Tennisnerd's Technical Assessment

Performance Characteristics

Zero's power response impressed Jonas with its lively feel. The string has enough energy to help your shots but maintains control when you need it.

The string's snapback capability particularly stood out during testing. When you hit with topspin, the strings slide and then snap back into position faster than standard polyesters. This creates the bite and rotation that modern players demand.

Tension maintenance proved to be one of Zero's strongest points. Jonas noted that "tension maintenance was very good" compared to other strings in its category. While many polyester strings lose their feel after just a few sessions, Zero keeps its lively characteristics much longer.

He experienced a "very nice sound, very nice sensation impact" when hitting with Zero. This sensory feedback gives you confidence in your shots and creates that satisfying connection between racket and ball.

Despite its six-sided shape, which typically increases stiffness, Zero remained comfortable, which makes it great for extended play sessions without arm issues.

Compatibility with Different Rackets

Jonas's testing revealed how Zero performs across the spectrum of rackets, helping players understand which setups maximize the string's benefits.

Control-Oriented Frames (18x20 patterns)

The Head Radical MP with the 16G gauge provided the best results. Jonas wrote that Zero "worked absolutely best in the Radical MP. I got good performance, confidence and comfort from it." He felt this setup gave him "enough confidence to take into a tournament."

Jonas would personally use Zero to "get some more action and power from 18×20 control racquets like my old Prestige MP." This shows how Zero can add liveliness to traditionally control-oriented frames.

Power-Oriented Frames (16×19 patterns)

In the Head Extreme Tour with the 16G gauge, Jonas found Zero to be quite lively. This more powerful racket seemed to amplify Zero's energy, which may not suit all players.

The Babolat Pure Aero Rafa also received the 17G gauge treatment. Jonas noted that for "more powerful racquets, I prefer a deader, more control-oriented string because I felt like Zero was relatively lively."

Comparisons to Market Alternatives

He said the string is "kind of a Yonex Poly Tour Pro, Poly Tour Rev type of string, softer still gives you good bite some control and it's kind of in that category."

However, Zero offers a different feel compared to popular alternatives. Jonas specifically mentioned it feels more comfortable than strings like Hyper-G and Lynx Tour while maintaining good performance characteristics.

He also wrote that Zero remains controlled longer than softer strings like “Hyper-G Soft and Wilson Revolve Spin”.

Overall Assessment

Jonas summed up Zero perfectly by saying it is "a spin-friendly polyester that doesn't break your arm and holds tension well." This combination addresses the main complaints players have with traditional polyester strings.

The string works best for players who want to add more power and spin to their game without sacrificing comfort. If you're the type of player who likes to grip the ball and hit with heavy topspin, Zero gives you the tools to do exactly that.

Conclusion

Jonas's testing of Zero across multiple rackets and court sessions revealed a polyester string that delivers exceptional snapback, responsiveness, and spin potential.

For Jonas, Zero proved most effective in control-oriented frames like the Head Radical MP, where its lively characteristics added power without overwhelming the setup. However, if you are an aggressive baseliner or big server, Zero in an open pattern racket might be the combination you need.

What sets Zero apart, according to Jonas's analysis, is how it solves multiple problems simultaneously. The string maintains playability longer than other polyesters, provides the spin and snapback of shaped strings, and does so without the arm discomfort that is often present.

If you're looking for a polyester that has amazing snapback, grips the ball effectively and maintains its performance, try Zero today and feel the difference.
