Best Tennis Strings for Holding Tension

April 7, 2014

With the introduction of so many co-polyester strings in the past several years, undoubtedly many co-polyester strings play softer than the first generation strings but many also lose tension very rapidly. Some strings and string brands that come to mind is the Dunlop Black Widow string, Poly Star Energy and Polyfibre Black Venom as just 3 top-selling strings that drop their tension fairly quickly.

We here at The Tennis Depot do carry several strings that are known best for retaining their tension and those are Signum Pro Poly Plasma, Signum Pro Hyperion and Signum Pro Tornado all from Germany-based Signum Pro string brand. Another excellent string we offer for retaining tension is the Genesis Typhoon and Genesis True Grit, 2 excellent shaped and twisted co-polyester strings that maintain their tension. In addition, the NEW Topspin Culex Squarestring (made in Germany) a square-shaped co polyester string, similar to Solinco Tour Bite (made in Taiwan) but holds its tension better!  One last one that comes to mind is the Topspin Cyber Blue. One thing all these strings share in common that they are made in Germany to the highest quality standards and all maintain their tension VERY well, in comparison to other co-polyester tennis racquet strings on the market today.

Comparison String Review: Genesis Spin X and Signum Pro Tornado

November 20, 2009

As explain in an earlier post, the tennis string market has gone through some significant changes in the last few years.  It wasn’t long ago that Natural Gut reigned supreme as the top choice (if you could afford it) for players of all levels.  Virtually all pro’s on tour had variations of “Gut” in their frames to achieve great ball feel.  Today, there has been a great shift towards the newest string composition: Polyester.  Recent polyester strings offer offer supreme ball control at high swing velocities along with great durability. Looking even further, “textured” polyester strings are currently in the tennis equipment lime light as they provide all the benefits of regular polyesters with added ball bite and spin.  Two such recently released textured polyester strings that reign at the top of their class are Genesis’ Spin X and Signum Pro’s Tornado.

Let me preface my review of these strings by stating that they are two of the most advanced 3rd generation polyester strings on the market; players can’t go wrong with either string in their racquets.  That said, there are some subtle differences that can help you decide which string better suits your individual game style and needs.

Genesis Spin X:

Genesis is a relatively new string brand that hit the ground running as they initially released Spin X as their “flagship” string.  During stringing, Spin X is resistant to kinking and lacks extreme coil memory which makes for easy installation.  The construction method Spin X is a very sophisticated process that allows the already octagonally textured string to be twisted around the axis.

From a playing perspective, the string provides great access to spin with its rough and twisted surface.  I was able to achieve great ball bite for heavy topspin while maintain pinpoint control over shot location, especially at high swing speeds.  Volleys are crisp and “plow through” is still substantial, something textured strings can often lack.  Spin X is also less resistant to string notching and after an initial break-in period holds playing characteristics until it breaks.


  • Great blend of control / spin
  • Resistant to notching compared to other textured poly’s
  • $ – very affordable for high-end polyester

Signum Pro Blackline Tornado:

This is Signum Pro’s new flagship string that continues a tradition of great polyesters from this company.  Signum Pro’s previous strings (such as the entire Poly Plasma Line) are known to provide great tension maintenance and a consistent string bed right off of the stringing machine.  Tornado continues with these characteristics, and adds great access to spin with its textured / twisted surface and substantial power for a polyester string.

Installation is slightly more tedious than Spin X as Tornado has a rougher texture; this shows up as an added benefit on the court with extreme amounts of ball bite.  Where Spin X blends control and spin, Tornado is a mixture of power and spin – so much so that I would recommend stinging 2-3 pounds tighter to help offset the “pop” off the string bed.

On court I was able to hit very heavy topspin shots off both sides, and my slice shots stayed low and dug into the court on the other side.  My kick serve jumped up like never before, often forcing my opponents to hit returns above their shoulders.  This added spin does come with a couple downsides, in that I found it difficult to flatten out my strokes at times as the extra texture likes to really bite into the ball.  Also, Tornado played extremely well in my racquet from the start, but after some time began to notch and lose its playing characteristics.


  • Extreme amounts of spin from anywhere in the court
  • Great power and pop, especially for a polyester
  • Maintains Poly Plasma-like tension maintenance

All in all, both strings are great choices for those looking to break into the world of textured polyester strings.  The best way is to truly give them a try yourself and see which one better suits your game style.
