Yonex Poly Tour Pro String Review

A co-polyester string from Yonex that is designed for comfort. How did it perform?

I had heard good things about Poly Tour Pro, and I was looking forward to trying it out. The main selling point of the string as advertised was comfort, but ironically, the best feature turned out to be something completely different.

I so enjoyed playing with Poly Tour Pro that I am seriously considering switching to it permanently, away from my current choice of Head Hawk. How did the playtest go?

Yonex Poly Tour Pro Specification

Solid power, spin and comfort […] For players of all swing-speeds looking for a soft, all-round string. How Yonex pitches their Poly Tour Pro String.

String Specs:

  • Co-poly monofilament
  • Round cross-section
  • Gauges – 1.15 mm, 1.20 mm, 1.25 mm, 1.30 mm
  • Colours – “Flash” yellow, graphite and blue

I play with a Head Prestige S from 2018. Prestige racquets are Head’s series for precision and control and typically come with a smaller head size as a result.

Mine has a 95 square-inch head with a 295 g unstrung weight. It also has a 16×19 string pattern and is 0.66 points head-light.

I had Poly Tour Pro strung at 55 lb with a 1.30 mm gauge, on which I also placed Head’s medium-level dampener – Pro Damp.

So how did Yonex Poly Tour Pro play? Let's take a look with a full playtest and review.

Initial Thoughts and How It Felt

On a sunny day, I took to an artificial clay court with a friend where the air was hot, and the sand was dry.

I was expecting from what I had read for the string to have a decent level of comfort, but it actually felt a bit stiff compared to what I was used to.

Ball pocketing was minimal, but it wasn’t uncomfortable either. Physically hitting with the string caused no discomfort in my arm.

As I started to warm up, any apparent stiffness was still there, but it seemed to fade into the background of my attention, and instead, I felt incredible access to power.

The ball was not only going faster, but it also had considerably more weight to it when landing on my opponent’s side of the court.

The string was unforgiving –  if I didn’t hit it right in the sweet spot, I felt a slight decrease in power.

It reminded me a lot of Tecnifibre’s T-Fight frame, where if you were precise with your shots and watched the ball carefully, the rewards in speed were great. But if you miss-hit a ball, you could easily lose some rally dominance. I also noticed less access to spin.

On my forehand, particularly, I couldn’t generate the same amount of topspin with the same technique, and my slices had less backspin.

Nevertheless, this didn’t pose any real problems, and I enjoyed watching the ball pop off my racket. I quite like the colour, and it was a gentler hue to the bright orange string I had previously reviewed.

I imagine it would aesthetically go well with most frames, and the other choices of graphite and yellow provide a nice degree of variation.

Nick Kyrgios, of course, opting for the “flash” yellow as described by Yonex, uses a version of Poly Tour Pro with a 1.20 mm gauge.

Though the snapback was decent, if players wanted a more all-around string with the same power, then opting for a lower gauge such as the 1.20 mm would help in generating topspin.

How It Played

On the forehand side, I found Pro to be flat and aggressive with some but not a great deal of topspin.

In defensive situations where I was pushed back, it wasn't easy to generate the looping topspin needed to stay in the rally.

Instead, some of my forehand shots were floaty, landing mid-court, which gave my opponent an easy ball to attack.

I have adapted slightly and have tried to hit through the ball more to compensate for the lack of depth, but I found myself making some unforced errors as a result.

However, I don’t see this as a major downside. Poly Tour Pro gives so much power and weight to the ball in neutral and attacking rallies (rather than defensive ones) that it encourages you to step forward, take it early and be aggressive.

As a result, this increased urgency has led me to play more on instinct and finish points quickly with the knowledge that attempting a flat forehand down the line, for example, will be greatly aided by the string.

Mentally I feel better on the court, not getting stuck in long, drawn-out exchanges but playing with freedom and pace.

On the backhand side with my one-hander, it was a similar story. A topspin groundstroke had enough but not loads of spin, whereas a flatter shot had extra weight and speed.

I was able to pull my opponent far out of position with a cross-court shot and move forward to finish the point. Players who like to hit with a lot of topspin on their backhand may find their shots lacking depth.

So many young players at my local club play with a flat, double-handed backhand and seem to slap the ball with no apparent loss in precision.

I imagine Poly Tour Pro would be decent here, providing consistent depth and shot tolerance for rallies on the backhand side, even with increased speeds.

There was also less backspin for the backhand slice, though tactically compared to the forehand side, it wasn’t so much of a problem. I found my slices and drop shots staying low and biting into the ground enough to help win the point.

On the serve, I really had to watch the ball carefully. Before, if I had not hit my serve right in the sweet spot, the ball would still have a fair degree of speed.

Here with Poly Tour Pro, a badly-timed serve would lead to a weak ball gently drifting into my opponent’s service box. But with proper contact, the ball fired off the racket, increasing the probability for aces and successful “serve plus one” tactics.

My serve really is not the best in the world, and it can be my weakest shot. Sometimes, I can send a flat serve down the “T” with no problem or a slice or a kick out-wide.

Other times I choke and almost pat the ball over the net in fear of making an error. If you’re confident with the serve and have a nice fluid motion, you will have no problems with Poly Tour Pro.

If you are like me and sometimes you can’t do the proper stroke, you may find yourself open to attack at times.

Overall, particularly for groundstrokes, Poly Tour Pro is incredibly precise, offering great control. I was able to take greater risks and aim for space close to the lines, taking more time away from my opponent. This gives you further confidence to go for winners with the reassurance of accuracy.

Around the net, Poly Tour Pro dealt with volleys well. The punch-slice technique Federer employs for volleys came off particularly fast.

Because of the slight stiffness of Pro, I found softer shots in the forecourt more difficult. You really had to soften your hands for light touches and pickups.

However, the firm string bed makes for good energy transfer for close deflections and reflex shots when tight to the net.

Durability and Price

The string has decent snapback, and I never had to move them back into position. There was a small issue with tension.

I asked for the tension to be set at 55 lbs. However, after an hour of play, the tension had decreased slightly more than I'd expect from a polyester.

Over the course of the week, I felt the strings gradually slacken, and by the last session, it may have been time for a restring. A hybrid setup may last slightly longer with the Poly Tour Pro on the crosses.

Nevertheless, the value for money is great, with the price being $11.60 (~£8.40) for a 12 m set. A very reasonable cost for a string that would easily boost an aggressor and counter-puncher game.

Who Is This String For?

Pro is a great choice for players looking to be aggressive, take the ball early and finish points quickly. Though there were some issues with generating topspin when pushed behind the baseline, the string still produces enough for those who like to hit with great shape on the ball in a neutral rally situation.

If you like hitting flat forehands and backhands, Poly Tour Pro will complement your game well. I would recommend this string for intermediate players who can tactically adjust to the lack of spin when on the defensive.

If you’re looking for more comfort, I wouldn’t say this was the best option. Though Yonex highlights comfort as a main feature of Pro, it actually plays a little stiff, especially during delicate shots around the net.

Final Thoughts

Yonex Poly Tour Pro can be unforgiving, hard to defend with and perhaps a little stiff, but I love it. It has superb access to power, encouraging attacking and decisive tennis. Mentally I feel so much better playing with this string and really going for shots.

I think the blue is a nice colour change without being too “out there”, and for what it is, the price, the string is great.

I was a little disappointed with the slight loss of tension, but after the test, I can still play well and keep my opponent on the back foot. It’s definitely not an all-around string, but for hard-and-fast tennis, it’s great.


  • High levels of power
  • Very precise


  • Less access to topspin
  • Could have more feel for softer shots at the net
  • Loss of tension after the first session and noticeable at the end of the week

  1. Off-topic but about the post’s image.
    I was alwys impressed by Tiafoe’s forehand backswing. Looks a bit like Delpo or Kyrgios and maybe Khachanov or Sock? Or it’s his own?

  2. Cheers for the review Alex. I have used Poly Tour Pro a few times over the last year, used it when I reviewed the previous generation Vcore 98 –

    I found it quite jumpy but this might have also been due to the Vcore which I struggled with early to control. I should really try it in the Pro Staff I have been using as well, I have Solinco Confidential in it now and will be doing a review of that shortly.

  3. Keep this one to the Poly Tour Pro. The last post can be corona stuff seen as though it was vaguely related to the Olympics.

    You can also find me the data that unvaccinated people drive mutations 😀

  4. [OFF-TOPIC] I guess, you will not follow OL with a dedicated article, Jonathan?

    What a big tournament! they are 64 in singles. Only 10 from Top20. But 22 ranked 100+, including 2 ranked 500+. Rather impossible in any Masters tournament.

    I’m wondering, what does the seeding in OL tournament?
    What will be worth the title?

    Good, that neither Fed nor Thiem are there

    Who is your favorite for the title, hahaha … ???

  5. Ever heard of Artemisia annua? The extract of this plant should have shown to be effective in killing Covid in lungs of infected people.

  6. Another thought on Federer and USO.
    Maybe the best would be for Fed to fall in the ranking, so he can get Nadal or Djoker in first/second round, so he is still fresh and without pains and can give it all. Even if losing, there would be a chance for an epic match. There will be not much more such chances. And should Fed have some chance to defeat a big rival, he needs to do it early. Even in the worst case, if he would need to withdraw after such a win, it would be at least some great accent in New York (be it farewell or not).
    Jonathan will probably know, how low Fed could fall in the ranking before USO.
