Nemesis: Control for the Advanced Player
The Pro-Strings Nemesis is a control-oriented string reminiscent of the popular 'All Power' strings. It offers excellent control and a medium-firm feel, making it ideal for advanced players. I tested the 1.25 gauge in an East Zone Tour frame. Its price point of £100 per reel is competitive within the premium string market.

The Nemesis boasts impressive durability and decent tension maintenance, though some tension drop is expected. Manufactured in Germany, it provides a premium feel and is available in 1.35, 1.30, and 1.25 gauges. Overall, it's a high-quality choice for those prioritizing control.

Pentagon: Spin-Friendly and Durable
The Pro-Strings Pentagon (1.25 gauge) is designed for spin. Tested in a Head Clash racquet, a known string-breaker, it surprisingly held tension exceptionally well, demonstrating great durability. Its unique five-shaped construction enhances spin generation.

While offering impressive performance and tension maintenance, the Pentagon has a stiffer feel. Players prone to arm pain might prefer a lower tension, or consider alternative options, but overall its durability within a high-tension racquet is noteworthy.

Firepower: Power and Arm-Friendly Feel
The Pro-Strings Firepower string offers a softer, more powerful, and lively feel than the Pentagon. While its tension maintenance is good, it's not quite as impressive as the Pentagon. This makes it a better choice for players who want a more arm-friendly option.

Tested in the Clash racquet, the Firepower provides a noticeably softer impact, making it a good alternative to the Pentagon for those seeking a balance between power and comfort. It's more lively and forgiving and thus a solid choice for those seeking assistance from the string itself.

Demon: Co-poly with Extra Bite
Pro-Strings Demon is a co-poly string with a noticeable 'snap' and excellent ball bite. Its performance is quite similar to the Pentagon, providing solid control and spin. The string is reminiscent of the popular MSV Focus Hex Ultra.

It is a good option for string breakers who hit with heavy topspin. This string offers excellent spin generation and a performance similar to the Pentagon. The overall feel is excellent for those seeking enhanced spin and control.

Attu: Soft and Comfortable
The Pro-Strings Attu is arguably the softest string in the lineup, providing a comfortable playing experience. The feeling is subjective, varying with racket and tension. Tested in a Babolat Pure Drive, it delivered good control and a soft impact, which is similar to the Firepower string.

It’s a suitable option for string-breakers, softer than the Demon and Pentagon. The lack of harshness on the arm makes it particularly appealing, even at higher tensions. Overall, this string delivers great comfort and decent bite.

Pro-Strings Multifilament: A Solid Hybrid Option
The Pro-Strings multifilament string was tested in a hybrid setup with Luxilon Natural Gut in an Encode 6195 racquet. It offered more power than the natural gut, feeling similar to a Kirschbaum Gut Feeling multifilament.

The multifilament showed unexpected durability for a 1.20 gauge, surpassing initial expectations. Although the natural gut provided superior feel and control, the multifilament was a strong contender, providing a powerful alternative in a hybrid setup.

Overall Conclusion: A Strong Contender in the String Market
Pro-Strings offers a diverse range of high-quality strings catering to different playing styles and preferences. Each string provides unique characteristics, from the control-focused Nemesis to the spin-enhancing Pentagon and the comfortable Attu. The multifilament also adds versatility.

The price point is competitive, offering excellent value for the quality. While personal preferences influence string choice, Pro-Strings presents a solid option for players seeking durable, high-performing strings. Consider individual string features to find your ideal match.
