The control benchmark is Luxilon ALU Power 125 — the most-used string on the professional tour and the one every other polyester is measured against. If you want control without ALU's harshness, Yonex Poly Tour Pro is the softest polyester sold. If you are below 4.0 and want more control than your current setup, the honest answer is usually a tension change rather than a new string.
What control actually is
Not accuracy. Control, in a string bed, is low power plus a predictable launch angle. A low-powered bed means you can accelerate fully through the ball and it still lands inside the baseline; a predictable launch angle means the same swing produces the same depth, shot after shot.
That is why polyester dominates this page. Poly is a stiff monofilament with very little elasticity, so it returns much less energy to the ball than a multifilament does. The ball leaves slower and flatter for the same swing. If you are hitting long, that is exactly the fix.
Why control is only useful above a certain swing speed
A low-powered string helps a player who produces more pace than they can keep in the court. Give it to a 3.0 who is already hitting short and it makes them hit shorter, and they compensate by swinging harder, which degrades technique.
The test is the same one we use on the 4.0 racquet page: think about your last three matches. Were your errors mostly long, or mostly short and in the net? Only “long” means you need control.
The exception on this page
Prince Synthetic Gut is here deliberately, and it is not a control string in the polyester sense. It is the default club pro-shop nylon: cheap, predictable, moderately soft, and nothing like as low-powered as a poly. It is on this list because for a 3.0–3.5 player who finds polyester harsh and unplayable, a fresh synthetic gut strung two pounds tighter delivers more usable control than a dead ALU bed ever will.
Control is relative to what you can actually swing with.
Comfort is the bill
Every poly on this page is stiff, and stiff string beds transmit shock. If your arm has ever complained, read strings for tennis elbow before you buy any of them, and consider a hybrid: poly in the mains for the control, a multifilament in the crosses for the comfort. That setup is the right answer for more club players than either extreme.

Pros
- +The reference polyester — if you have ever read a string review, it was compared to this
- +Exceptional control: it holds a flat drive in the court at full swing speed
- +Crisp, precise feedback that tells you exactly where you made contact
Cons
- −Stiff. A full ALU bed in a stiff frame is the classic tennis-elbow recipe
- −Loses tension faster than its reputation suggests — plan on restringing before it feels dead
Don't buy this if…
…you are below 4.0 or have any arm trouble. Buy a multifilament; you will hit a better ball and keep your elbow.
Spin with tension stability
HEAD Lynx Tour 17g (set)
Hexagonal co-polyester17g / 1.25 mm40 ft setTension-stable
A hexagonal poly that stays lively longer than most — the thinking player's alternative to RPM Blast, usually at a lower price.

Pros
- +Hexagonal profile bites the ball for spin in the same way RPM Blast's octagon does
- +Holds tension unusually well for a polyester, so the string bed stays consistent for longer
- +Consistently cheaper than the Babolat and Luxilon equivalents
Cons
- −Stiff — a poly is a poly
- −Less feel than a softer co-poly like Hyper-G Soft
Don't buy this if…
…comfort is your priority. No shaped polyester belongs in an arm-friendly setup.
Comfortable polyester
Yonex Poly Tour Pro 125 (set)
Silicone-infused poly1.25 mm40 ft setSoft co-polyester
The most comfortable polyester sold. Yonex's silicone-infused poly is the bridge between a control string and an arm you can still use tomorrow.

Pros
- +Silicone infusion genuinely softens the string without turning it into a multifilament — the best poly option for a player with mild arm sensitivity
- +Round profile means it is gentler on the frame's grommets than aggressive shaped strings
- +Holds tension well for a soft poly
Cons
- −Round profile gives up spin relative to a shaped string
- −Still a polyester; it is not in the same comfort class as NXT or natural gut
Don't buy this if…
…spin is the whole reason you are going to poly. Buy RPM Blast or Hyper-G instead.
Power baseliners
Babolat Pure Drive (Wimbledon 11th Gen)
100 sq in head11.2 oz strung16x19 patternRA 69 stiffness
The most popular performance racquet in the world, in a Wimbledon colourway. If you want free power from a 100 sq in frame, this is still the benchmark.

Pros
- +Enormous, effortless depth — the stiff beam returns energy rather than absorbing it
- +16x19 pattern plus that power makes a genuinely heavy topspin ball once you can brush up on it
- +The most widely demoed frame in tennis, so coaches and stringers all know how to set it up for you
Cons
- −Stiff. The Pure Drive's reputation for being hard on the arm is earned, and a poly string makes it worse
- −This is a limited-edition colourway at a limited-edition price — the standard Pure Drive is the same frame for less
Don't buy this if…
…you have ever had tennis elbow. Buy the Clash 100 instead; it is the same job description with none of the shock.

Pros
- +The cheapest per-restring cost of any string here by a wide margin
- +Solid core with a Duraflex wrap: more durable than a plain nylon, softer than any poly
- +Completely predictable — nothing about it will surprise or disappoint a developing player
Cons
- −No standout property: less control than poly, less comfort than multifilament, less spin than either

Don't buy this if…
…you are 4.0 or above. You will feel the lack of control within a set.
The five, by how they control the ball
| String | Type | Control comes from | Comfort |
|---|
| Luxilon ALU Power 125 | Co-polyester | Lowest power, crispest feedback | Low |
| HEAD Lynx Tour 17g | Hexagonal poly | Low power plus unusual tension stability | Low |
| Yonex Poly Tour Pro 125 | Silicone-infused poly | Poly control with the edge taken off | Moderate |
| Babolat RPM Blast 17g | Octagonal poly | Spin-driven control — the ball dips | Low |
| Prince Synthetic Gut 16 | Solid-core nylon | Predictability and a fresh bed, cheaply | Moderate-high |
Two kinds of control, and they are not the same
Depth control is what a low-powered string gives you: the ball lands where you aimed because the bed is not adding anything. ALU Power and Lynx Tour are this.
Spin-driven control is different: the ball leaves fast but the topspin brings it down inside the baseline, so you can hit harder with more margin over the net. RPM Blast is this, and it is why a spin string belongs on a control page at all.
Which you want depends on your swing. Flat hitters want depth control; topspin players get more usable control from the spin route. See best strings for spin.
Tension and gauge, the free adjustments
Before you change string, know that you can buy control with the two settings you are already choosing.
Tension up 4–5 lb flattens the launch angle noticeably and costs you power and comfort. Gauge up (16g rather than 17g) gives a slightly firmer, more controlled bed and lasts longer, at the price of a little spin.
Both are cheaper than a string change and both are reversible at your next restring. The tension guide walks through finding your number methodically, two pounds at a time.
Control strings die quietly
The thing that ruins a control setup is not the wrong string, it is an old one. Polyester loses tension and elasticity fast and then sits in the frame looking fine for months. A dead poly bed has lost the snapback and the consistency you bought it for, and it is harsher on your arm than the day it was strung.
If your depth has become unpredictable and your technique has not changed, suspect the string. See how often to restring.
The frame is half of it
A control string in a very powerful frame is a sensible pairing — it tames depth you could not otherwise keep in the court. A control string in an already low-powered control frame can leave you with nothing at all, pushing the ball to get it over the net.
If you play a control racquet and want more control still, the honest answer is usually to look at your technique or your tension rather than going stiffer again.
How we picked
We have not physically tested this gear
Everyone in this category says they tested twenty racquets. We have not tested any — and we say so. What we did instead: compiled the manufacturer-published specifications (head size, strung weight, string pattern, stiffness, outsole compound), normalized them, and scored each product against a published rubric weighted for the NTRP tier this page serves. The scores are judgments from documented research, not measurements we took, because we do not have a lab and are not going to pretend we do.
Questions
Frequently asked
What is the best tennis string for control?+
Luxilon ALU Power 125, the professional tour benchmark and the lowest-powered string here. Yonex Poly Tour Pro gives you most of the same control with meaningfully more comfort if ALU is too harsh.
Does higher string tension give more control?+
Yes, up to a point — a tighter bed deforms less and launches the ball flatter and more predictably. The cost is power, comfort and string life. Four to five pounds is a noticeable change; try it before changing string.
Is polyester the only control string?+
It is the most effective one, but control is relative to what you can swing with. For a 3.0–3.5 who finds poly harsh, a fresh synthetic gut strung slightly tighter delivers more usable control than a dead polyester bed.
