In the 2018 Junior Australian Open, the Yonex Poly Tour Spin Tennis String was one of the most used strings. This shows how effective it is on the court. 

For this string, there are eight Poly Tour options to choose from: 

  • Poly Tour Air is gentle and the softest of them all. This is because it has a shock reduction mechanism to reduce discomfort. 
  • Poly Tour Pro is the most popular Yonex Poly Tour tennis string. It gives a firmer touch and is also arm-friendly. 
  • Poly Tour Fire is your best option for firing up the snapback and spin. It also performs best for players who take full swings. 
  • Poly Tour Strike has the best ball control and tension maintenance.  
  • Poly Tour Tough is best for string breakers. It is tough, durable, and withstands heavy hits. 
  • Poly Tour Spin has Giga spin structure technology that increases its spin performance by about 14%. This helps control the ball’s direction and gives more control. 
  • Poly Tour Spin G is the firmest of them all. It uses silicone oil that is infused with filament technology to increase string movements. This results in extra spin on the ball.

Who Is It for? 

From the manufacturer’s description, it is meant for competitive players with rapid-fire attack shots and high swing speeds. These players already produce enough power, and all they need is better control to win the game. 

The Yonex Poly Tour Spin Tennis String works best with a frame that does not shudder on contact. Having this combination results in clean ball striking and follow through. 

Having control of powerful strikes gives you better shot precision and accuracy, which increases your odds of winning.

Also, players suffering from shoulder and arm pain should consider this product. It might not produce the intended amount of power, but it is gentle on your arm, and it will help them practice as they recover.

  • Pentagon shape 
  • Tension maintenance 
  • Different gauges  

The polyester monofilament is responsible for providing a powerful grip on the ball. This leads to better control. This monofilament is also easy on the hand. 

The Yonex Poly Tour Spin Tennis String has a pentagon shape that helps you get extra bite on the ball. This results in increased ball spin.  

Using the Yonex Poly Tour Spin Tennis String on your racket provides complete control over its tension. You can freely adjust the tension to the level that accommodates your playing style. 

There are different gauges of this product — 1.20mm, 1.25mm, and 1.30mm. When it comes to durability, the thicker the gauge, the more durable it is. 

The three different gauges accommodate different playing styles. For instance, the 1.20mm gauge produces the best ball spin, players prefer the 1.25mm for a hybrid, and the 1.30mm is best for a full bed. 

FORTIMO is a highly elastic polyurethane that features a fusion of resin filament that eliminates small gaps between the fibers. This makes the string more flexible and repulsive. 

The resin is also bonded to the filament using plasma. All these components work together to make the string durable.

Final Thoughts 

If we consider the upside of the Yonex Poly Tour Spin Tennis String, you will find that it has excellent ball spin, gives you more control, and is durable and comfortable. These qualities make it ideal for those familiar with tennis who know how to produce enough power. 

It is not the best option for kids and amateurs. Apart from it not generating much power, it loses tension fast. This means that you will enjoy the game at first, but the match might start becoming difficult towards the end. 

This string is recommended for professional players who understand their playing styles, strengths, and weaknesses. This means the ones who know what string gauges to use under which conditions, as well as those who know how to install the strings and quickly adjust the tension.
