TRU PRO Ghost Wire: Super Soft Poly String

TRU PRO Ghost Wire is marketed as one of the softest co-polyester strings available. The design targets players who want the benefits of a poly string—tension stability, durability, and bite—without the stiff feel common to some harsher poly strings. The string’s new-generation polyester compound focuses on arm-friendly performance, aiming to minimize shock during long rallies while maintaining control on depth and direction. Its round, slick surface enhances string movement, which can simplify hybrid setups that pair Ghost Wire with other string types to fine-tune feel and spin.
Key specifications include a 16-gauge (1.27 mm) profile and a 12.2 m length, which makes it versatile for both one-piece and two-piece string jobs. The string is positioned for players at all levels seeking a comfortable but spin-capable option, from club players to tournament competitors. In practice, players report a soft response with reliable durability, enabling aggressive swings without excessive vibration. Stringing at mid-to-high tensions can amplify control while preserving an easier feel on impact.
Tier One Ghost Wire: Ultra Soft Poly String

The Tier One Ghost Wire version is the same Ghost Wire family with a thinner 18-gauge profile (1.17 mm) and a 12.2 m length. It is described as one of the softest poly options on the market, prioritizing arm-friendly response while preserving the ball bite that players expect from a co-polyester string. This variant is well-suited for players who want maximum comfort on impact, particularly during long matches or harsh playing conditions. It maintains good tension stability and durability, offering reliable performance across rallies and hybrid setups.
Play-ready characteristics include a focus on comfort with adequate control for spin and depth. Because of its softer construction, it tends to pair well with multifilament or natural gut in hybrids, providing a smoother transition between strings. The 1.17 mm gauge helps you feel the ball and generate spin with less mass behind each shot, which can be advantageous for players with flatter strokes seeking more bite on the ball without excessive vibration.
Luxilon ALU Power Soft 125: Soft Poly String

Luxilon ALU Power Soft 125 is marketed as a softer version of the standard ALU Power line, designed to improve comfort and playability. The 125 indicates a lighter or softer composition relative to the main ALU Power family, delivering a noticeably more forgiving feel while maintaining the renowned control and spin potential associated with Luxilon. This string aims to reduce arm fatigue during extended rallies, making it a practical choice for players with sensitive elbows or those who string at higher tensions for added control.
In practice, ALU Power Soft 125 offers a balance of soft feel and dependable performance. It is well-suited for players who favor heavier topspin and aggressive swings but want a more forgiving impact. The set is commonly used in a variety of playing styles, including baseline power play and modern all-court strategies, and is amenable to hybrid setups that preserve spin while softening overall impact.
Solinco Hyper-G Soft: Spin-Optimized Soft Poly

Solinco Hyper-G Soft is positioned as a softer variant of the popular Hyper-G line. The string uses a monofilament copolyester construction with a distinctive shape intended to maximize ball bite and top-spin generation. While it remains within the poly family, the soft version is designed to provide more comfortable responses on contact, making it a practical option for players who string at moderate tensions and want a smoother feel on impact. The string is available in multiple gauges (16L 1.25 mm, 16G 1.30 mm, 17G 1.20 mm, 18G 1.15 mm) and comes in a standard 40 ft length, suitable for most rackets and stringing preferences.
In play, Hyper-G Soft emphasizes spin potential and directional stability with a more forgiving feel compared with the original Hyper-G. It suits players who rely on heavy topspin and aggressive court coverage but need a touch more comfort in long rallies. The surface remains fairly slick to support consistent depth control while preserving the string’s resistance to movement, which is favorable for accuracy during fast exchanges and open-stance swings.
Luxilon Big Banger ALU Power Soft 16 Gauge: Soft Poly

Luxilon Big Banger ALU Power Soft 16 Gauge stands out as part of the ALU Power line with a focus on softer feel and improved comfort. Descriptions highlight its 16-gauge construction and a composition that blends a copolymer or nylon matrix with fluorocarbon resin and aluminum fibers, producing a durable string with enhanced feel for poly players. The dented and textured surface adds bite on contact, contributing to higher revolutions per second. It is frequently recommended for hybrid setups where a softer poly is paired with a more aggressive or higher-titched string to balance spin, power, and arm comfort.
The product is commonly sold in a two-pack, offering extended use and consistent performance across stringing cycles. A common application is in high-spin, aggressive-baseline play where players want a forgiving poly string that still delivers strong spin and control. The soft character can help reduce shock on off-center hits, while maintaining the durability needed for heavy topspin rallies.
Buying Guide
Choosing soft poly strings involves balancing comfort, spin, and durability. Arm-friendly feel often comes with trade-offs in tension stability and power. Understanding your playing style, stringing routine, and comfort needs helps identify suitable options among soft poly strings.
- Softness and comfort: Softer poly strings reduce shock but can feel less lively on contact; their feel is influenced by gauge and construction. If arm comfort is a priority, look for 17G–18G or “soft” label products, and consider a slightly higher tension to maintain control.
- Spin and control: Monofilament copolyester strings typically offer strong spin potential due to their shape and bite. For heavy topspin players, a string with a pronounced surface texture and a slightly softer profile can sustain bite while remaining comfortable.
- Durability and tension stability: Durability varies by brand and construction. Co-polyester strings usually hold tension well and resist snapback rotation, but extremely soft variants may wear faster under aggressive play. Consider a hybrid setup to extend life while preserving feel.
- Gauge and playing style: Thinner gauges (18G, 17G) are more comfortable and spin-friendly but wear out faster. Heavier gauges (16G) provide more durability and stability, which is beneficial for players who swing hard or string at lower tensions for more power.
- Hybrid setups: Many players use a soft poly in the mains with a different string in the crosses to balance feel, durability, and spin. For example, pairing a soft poly with a multifilament or natural gut can enhance comfort while maintaining depth and power.
- Playing level and health considerations: All-level players can benefit from arm-friendly strings, especially those prone to elbow or shoulder discomfort. If pain persists, consult a coach or medical professional and consider adjusting string tension and grip size along with string choice.
How to choose among the five featured strings
- If maximum arm comfort is top priority, consider Tier One Ghost Wire or TRU PRO Ghost Wire for their soft feel and good durability.
- For players seeking a balance of comfort and classic Luxilon control, ALU Power Soft 125 offers a softer texture with dependable playability.
