The flare-up usually isn't the string you chose — it's the string you kept
Most sudden arm pain doesn't come from picking the "wrong" string. It comes from playing a polyester that has gone dead. A fresh poly is reasonably forgiving; the same string at 15-plus hours has lost its elasticity and dumps the shock it used to absorb straight into your wrist and elbow. So before you spend on natural gut, ask the cheaper question first: how old are your current strings?
If you play poly, cut it out roughly every 10–15 hours whether or not it has broken. If you've never done this, it's the single most effective change you can make — at zero cost.
Once your strings are fresh, choice sets the baseline. And the choice isn't simply "soft string good, poly bad." Stiffness is a spectrum, and where you land on it should depend on your budget, how much spin you need, and how often you're willing to restring.
The 5 Best Strings for a Sensitive Wrist
Comfort runs on a ladder: natural gut (~112–125 lb/in) and multifilament (~125–140) are the softest, modern soft co-polys (~170–200) bridge the gap, and stiff polyester (~220–235) is the usual culprit behind wrist trouble. Our five picks span that ladder so there's a fit for every game and budget — each is flagged arm-friendly in our database (of 29 total). Tap any name for full specs and scores.
Wilson NXT
Best overallThe smartest first switch off polyester. A gut-like multifilament that's plush enough for a sore wrist yet affordable and durable enough for weekly play — top-tier comfort with none of the gut price. If you only try one string on this list, start here.
Babolat VS Touch
Softest feelNatural gut is the most elastic, shock-absorbing bed there is. If your wrist is fragile and budget is no object, nothing is gentler — and the power and touch are unmatched. The only catch is cost and its dislike of damp conditions.
Tecnifibre X-One Biphase
Most powerOne of the plushest multifilaments made, with near-gut power and feel. The pick for flatter hitters who want maximum comfort without losing pop — though, like all multis, it frays faster than poly.
Tecnifibre Triax
Best arm-friendly polyProof a poly can be kind to your wrist: far softer than standard polyester, with the control and durability multifilament lacks. Ideal in a full bed for players who want a forgiving string that still lasts, or in the crosses of a hybrid.
Solinco Hyper-G Soft
Best for spinFor the topspin player who needs bite but can't take a harsh string. High spin with a noticeably softer impact than regular Hyper-G — just string it on the low side to get the most comfort out of it.
Two honest notes. The gut and multifilaments (#1–#3) are the softest but lightest on spin and wear fastest — restring often if you hit heavy topspin, or run one in the mains of a hybrid. The soft co-polys (#4–#5) are the value play for spin players, but "soft" is relative: pair them with a low tension and a frame that isn't ultra-stiff, or much of the comfort gain disappears. Two more arm-friendly co-polys worth a look are Luxilon ALU Power Soft and Solinco Tour Bite Soft.
Hybrid Combos and the Right Tension
Want the comfort of a soft string with even more spin and durability? Use a hybrid: natural gut or multifilament in the mains for feel, a soft co-poly in the crosses for bite. One caveat that follows from the opening — a hybrid is only arm-friendly while its poly stays fresh. A dead poly cross can make a "comfort" hybrid harsher than a fresh full multi, so the 10–15 hour rule still applies.
Whatever you string, go lower. Dropping to roughly 44–50 lbs for a soft poly, or 50–54 lbs for gut/multi, lets the bed flex, lengthens dwell time, and absorbs more shock than a tight stringbed — a meaningful difference for an aching arm, and the main lever that makes a co-poly arm-friendly. For the full picture, see our Strings and Tension Guide.
Your frame matters too — arguably more than the string. A stiff racquet undoes most of the comfort you gain, and it's why even a soft poly can still hurt. See our guide to the best racquets for tennis elbow.
Common Questions
Can polyester strings be arm-friendly?
Yes — this is the part most guides get wrong. Traditional poly is stiff and harsh, but a modern generation of soft co-polyester (blended with softening additives) is far gentler while keeping poly's spin, control and durability. Strung low and in a frame that isn't ultra-stiff, a soft co-poly like Tecnifibre Triax, Solinco Hyper-G Soft or ALU Power Soft is a genuinely arm-friendly option — and far cheaper than gut.
What strings are best for tennis elbow?
It depends on your game. If your arm is fragile or you don't need spin, natural gut or a multifilament (Wilson NXT, X-One Biphase) is softest. If you hit with spin and want durability without gut prices, a soft co-poly strung low is the better fit. The one universal rule: avoid stiff poly played at high tension, and never play any string dead.
How often should I restring to avoid arm pain?
This matters more than most players realise. Polyester loses its shock absorption fast: cut it out roughly every 10–15 hours whether or not it has broken, because a dead poly is a leading cause of sudden arm flare-ups. Gut and multifilament hold up longer, but restring by feel — once the bed goes stiff or you lose tension, it's time.
What string tension is best for tennis elbow?
Lower is kinder. For gut or multi, drop into the 50–54 lb range; for a soft co-poly, go lower still, around 44–50 lb. Low tension lets the bed flex, increases dwell time, and is the single biggest factor in making any string — especially a poly — easier on the arm.
Natural gut vs multifilament vs soft poly — which should I choose?
Gut is marginally the softest and liveliest but costly and humidity-sensitive. A top multifilament gets most of the way for a third of the price but is light on spin and wears fast. A soft co-poly gives up a little comfort but wins on spin, control and durability at a normal price. For an intermediate spin player with a sensitive arm, the soft co-poly is usually the best all-round pick.
Can a hybrid setup cause tennis elbow?
It can, in two ways: if the poly is strung too tight, or if it's been left in past its life. A hybrid is only as arm-friendly as its freshest component, so keep the poly within the 10–15 hour window and string on the lower side.
