Choosing the right tennis string is often called finding the "engine" of your racquet because it is responsible for roughly half of its overall performance. Strings broadly dictate how much power, control, spin, and comfort you get out of every swing.
The four primary types of tennis strings I currently have in stock are broken down below along with their pricing including string job. A guide further below details how gauge and tension can impact your style of play.
Polyester strings consist of a single, solid strand of plastic extruded into wire-like strings. They are highly stiff and are currently the most popular choice among competitive intermediate, advanced, and touring pro players.
The Good: Exceptional control and spin potential. They slide against each other and snap back quickly, which generates heavy topspin. They are also highly durable against breaking.
The Bad: They are very low-powered, drop tension faster than any other material, and their harsh stiffness can trigger or worsen injuries like tennis elbow.
Solinco Hyper-G is a uniquely shaped co-poly string that boasts an impressive combination of spin and precision. Designed specifically for an ATP top 50 player, this medium firm string enables powerful hitters to make significant cuts on the ball without the risk of overhitting. Topspin players who prefer hitting balls that dive sharply and generate explosive off-court power will find this string particularly appealing.

Developed over several years of rigorous testing, Mach 10, stands as Solinco’s most technologically advanced string to date.

MULTIFILAMENT STRINGS
Multifilaments are constructed by weaving together thousands of tiny microfiber strands coated in a flexible polyurethane resin, attempting to closely replicate the performance of premium natural gut.
The Good: Superior comfort, baseline power, and feel. They absorb high amounts of shock and vibration, making them the gold standard for recreational players or anyone recovering from arm injuries.
The Bad: They offer much less spin potential compared to polyester. They also fray and snap relatively easily when used by heavy hitters.

NXT, one of the most popular and reliable multifilaments ever created, offers an exceptional blend of comfort, touch, power, and feel. According to Wilson, NXT boasts a 10% larger sweet spot compared to traditional synthetic gut, coupled with a remarkable 74% reduction in vibration. This makes it an ideal choice for players with slower to moderate swing speeds seeking enhanced power. Additionally, NXT caters to all types of players who appreciate the classic gut-like feel of a multifilament. It’s also an excellent option for polyester string users who want to incorporate a hybrid string. Tennis elbow sufferers in search of a softer and more comfortable string should definitely consider NXT. While the thinner 17-gauge version provides even greater comfort and feel, it may offer slightly less durability compared to the 16-gauge version.

SYNTHETIC STRINGS
Synthetic gut is an entry-level nylon string that generally utilizes a solid monofilament core wrapped in one or more layers of protective smaller fibers.
The Good: Incredibly affordable and versatile. It serves as a decent, cost-effective, all-around baseline string for casual beginners or budget-conscious club players.
The Bad: It does not excel in any specific performance metric—it lacks the power/comfort of a true multifilament and the spin/control of a polyester.
Prince Synthetic Gut w/Duraflex, with its exceptional all-around playability, stands as one of the most cost-effective strings ever made. While it may not be as soft and lively as a multifilament string, this robust core synthetic offers a comfortable playing experience along with adequate power.

Compared to the Prince Synthetic Gut Original, this string is slightly firmer and more durable.

The Good: Unrivaled elasticity, tension maintenance, and pocketing feel. It stays lively and retains its optimal performance properties all the way until it physically breaks.
The Bad: It is exceptionally expensive (often $40–$60 per set before labor costs) and vulnerable to extreme humidity or moisture.
An iconic natural gut string favored by many ATP and WTA Tour professionals, this premium-grade version offers an unmatched blend of power, comfort, and feel. It maintains remarkable playability even at higher tensions. While thicker in gauge, it provides enhanced durability and slightly reduced power compared to the 16-gauge version.

Understanding Gauge and Tension
Gauge (Thickness): Strings are measured by numerical gauges or millimeters.
Thinner strings (e.g., 17 or 18 gauge / 1.25mm or less) offer more power, feel, and spin, but break faster.
Thicker strings (e.g., 15 or 16 gauge / 1.30mm or more) prioritize control and longevity.
Tension: How tightly the machine pulls the string inside the frame (typically measured in pounds or kilograms).
Lower tension allows the string bed to stretch like a trampoline, resulting in more power and comfort.
Higher tension limits string movement, giving you more precise control over the ball's depth.
