Buying Guide
String Type And Feel
String type strongly influences feel and injury risk. Multifilament strings are built from numerous smaller filaments, delivering a softer, more forgiving feel and reduced vibration. They typically help players generate comfortable power and maintain a stable swing through contact. Polys, including co-polys, are stiffer and offer excellent durability and spin potential, but can transmit more shock if tension is high or if form is off. For intermediate players, multifilaments like Head Velocity MLT and Wilson NXT are good options for comfort, while a poly like TRU PRO Pure Rush can complement aggressive baseliners who crave bite and control.
Gauge And Tension
String gauge affects durability, spin potential, and feel. Thinner gauges (around 17-18) provide more ball bite and greater feel but wear faster; thicker gauges (16-17) offer durability and stability, especially at higher tensions. For intermediates, 17 gauge strings are a common compromise, balancing comfort with pace. Tension stability matters for dependable performance across practice and matches. Strings advertised as tension-stable often perform well for players who restring regularly or who want consistent feel under varying playing conditions.
Durability And Arm Comfort
Arm comfort is a key consideration for players who practice long sessions or suffer from elbow or shoulder fatigue. Multifilament strings generally dampen shock better than poly strings, reducing fatigue and the risk of overuse injuries. Arm-friendly options like Wilson NXT and GAMMA Verve Soft are especially suitable for players with sensitivity. While poly strings may last longer, they can increase the likelihood of vibration if not paired with proper stringing and technique. Assess your playing style and tolerance for vibration when selecting a string.
Spin, Power, And Control Tradeoffs
Spin potential tends to be higher with string designs that feature multiple filaments or specific constructions, like six-sided poly strings. For intermediates, a balance of spin and control supports all-court play and transition shots. Power comes from a combination of string type and tension; multifilaments usually offer smoother, controllable power, whereas poly strings provide pace and bite. Mid-level players should consider how often they rely on heavy topspin versus flat winners and pick a string that complements their preferred shot repertoire.
Maintenance And Longevity
Durability is a practical consideration. Polys often resist notching, maintaining performance longer under frequent stringing at higher tensions. Multifilaments may require more frequent restringing but deliver a more forgiving, arm-friendly feel. If you string often or use a bulk format, reel strings like the Velocity MLT 660′ can reduce maintenance costs. For players who value playability over ultimate durability, a high-quality multifilament such as NXT or Verve Soft can be a smarter long-term pick.
How To Choose For An Intermediate Player
Match your string choice to your typical play style. If you prioritize comfort and a smooth feel during long rallies, select a multifilament string with 17 gauge throughout the set, like Head Velocity MLT or Wilson NXT. If you want more spin and aggressive pace from the baseline and you’re comfortable managing potential additional shock, a poly option such as TRU PRO Pure Rush can complement your game. Consider your stringing routine, equipment maintenance habits, and any prior elbow or shoulder issues to determine the best balance of feel, durability, and performance for your intermediate level.
