To help you track down the best synthetic gut for your needs, I’ve pulled together a list of my favorites. The following are strings that I’ve playtested, organized by attribute.
Keep in mind that while I’ve selected each string that I found best aligns with specific performance criteria, others may also work well for that need. For example, while I’ve chosen Gamma TNT2 for power, Wilson Synthetic Gut Power and Head Synthetic Gut PPS are strong candidates.
Best Overall – Gamma Synthetic Gut
Gamma offers an extensive line of tennis strings, and one of their most popular is their synthetic gut, which strikes an excellent balance between affordability and performance.
Gamma Synthetic Gut is perfect for those who are new to tennis and looking for a reliable option or anyone in need of a budget string that delivers above-average performance for this type of string.
As a bonus, the string comes in three gauges, 16, 17, and 18, and a handful of different colors, perfect for kids.
Best For Spin – Gosen OG-Sheep Micro
Players looking for maximum spin on a budget and who want to avoid polyester tennis strings should check out Gosen’s OG-Sheep Micro.
Featuring a thinner solid core surrounded by a wrap of filaments, this string offers a slightly stiffer feel that delivers the best spin of any synthetic gut strings I’ve tested.
The price is excellent, and it comes in three different colors and gauges, giving you more options to dial in your ideal performance. For the best performance hitting topspin, go with the thinner 17 or 18 gauge, but keep in mind that durability will drop the thinner you go.
It’s worth noting that Gosen makes a variation on this string called OG-Sheep Micro Super, which features a slightly thicker core and more durable coating for better durability if needed.

Best For Power – Gamma TNT2
One of my personal favorites in the synthetic gut family, Gamma TNT2 is a premium offering with a unique co-polymer solid core, meaning it features nylon and additives for enhanced performance.
The string also features an outer layer of nylon wraps and a pearl nylon coating. Gamma tops it all off with TNT, their advanced thermal processing technology that bolsters the string’s resilience for improved playability, durability, and control.
One of the best synthetic guts I’ve tried, Gamma TNT2 delivers above-average power and surprising comfort. The string is also available in four gauges, including 15L, 16, 17, and 18, and various colors to suit most player preferences.

Best For Comfort – Wilson Synthetic Gut Power
Although Wilson Synthetic Gut Power delivers plenty of power as advertised, I find its best quality to be comfort as the most arm-friendly string I’ve tried in its class.
This string features a solid nylon core like many others on our list. However, it differentiates itself with high-powered bi-directional Nomex X-Bands or wraps layered around the core for enhancing energy return and responsiveness, resulting in a more lively response and improved feel.
Wilson Synthetic Gut Power comes in a handful of bright colors and two gauges, adding variety to the offering. Overall, it’s one of the best, outshining others with arm-friendly comfort.
If you’re looking for maximum comfort, I’d encourage you to check out some of my favorite multifilaments.
Best for Control – Head Synthetic Gut PPS
Synthetic gut tennis strings aren’t inherently the most control-oriented. Instead, they skew more on the power side of the spectrum. However, I’ve found Head Synthetic Gut PPS to deliver better control than many other strings in this category.
The string has a solid core layered with Head’s PowerStrip technology, a unique polyamide for greater resilience for a string that’s not underpowered but emphasizes control.
Head’s Synthetic Gut PPS comes in a few colors and two gauges to help further refine your selection. Overall, it’s a well-balanced synthetic gut that’s a solid option for control. Check out my polyester string recommendations if you’re looking for maximum control.
Best For Durability – Prince Synthetic Gut with Duraflex
Prince’s Synthetic Gut Original remains a staple in this string category, but their Synthetic Gut with Duraflex offers even better performance.
It’s an affordable solid core string that incorporates Duraflex wraps to stiffen up the string for a crisper feel that improves durability and control. For maximum durability, I recommend players go with the thicker 16 gauge.
As a bonus, this string comes in more colors than any other synthetic gut, making it perfect for kids or anyone looking for a custom look.
Best For Hybrid – Yonex Dynawire
Yonex Dynawire is an underrated premium synthetic gut offering that delivers excellent all-around performance and is a terrific option for pairing with other strings as part of a hybrid string setup.
You’ll find a high polymer nylon at the string’s core, surrounded by a thin metal film that improves resilience and power and a layer of outer wraps for enhancing comfort and durability. Yonex tops the string off with a silicone treatment that’s slick for improving snap back.
I’ve parid Yonex Dynawire with a few polys with excellent results. For better durability, I’d encourage you to opt for the 16 guage.
Although I didn’t select these three strings as the best for any single performance attribute, they’re all solid offerings that I’m comfortable recommending players check out.
- Babolat Synthetic Gut
- Dunlop Synthetic Gut
- Volkl Synthetic Gut
As you should expect from a synthetic gut string, these offer well-rounded performance in an affordable package.
