What’s The Difference?

As tennis players, you must constantly ask “what’s the difference” when it comes to tennis racquets and string! Well, as racquet technicians we ask the same questions!

This post is intended to showcase the differences of string in testing, not playing, however, some of the data may be noticeable to the player in certain situations.

What this graph shows us, in addition to our trying to save a tree by printing on the back of previously used paper, is that each of these stings will provide almost the same performance. This is indicated by the curve and how closely related the strings are.

Tensile Strength Comparison

The differences you do see here can be attributed to the gauge, or diameter, of the string, with the largest diameter (Tour Bite) having the highest tensile strength.  Down in the “hitting” displacement range (way below the 39.9mm!), there is very little difference.

The tensile strength can be a factor as the string begins to “notch” or otherwise come apart.  Each of the strings in this graph is monofilament so notching would be the failure mode in a racquet.

 

Head Prestige Tour 2021

This racquet has the potential to be the hottest new Prestige in a long time. The “Tour” series is not new to the Prestige line but this one has some differences that are meaningful, we think!

This new Tour is a 16×19 string pattern inserted into a 95 square inch hitting area! Compare that to the previous Tour with a 18×19 string pattern in a 99 square inch head(now the new Prestige MP)…so you can see where this one is headed!

All of the new Prestige 2021 racquets will come with the full cap system that has become the “iconic” Prestige accoutrement.  

Also included in the Prestige Tour is the Auxetic material and construction that is intended to provide a better feeling impact and maybe a little more “energy”.  The shaft has a slightly different geometry and is a little shorter than some other models, however, the graphics indicate the shaft is “elongated”.

The “box” beam is a relatively constant 22mm from start to finish and is beautifully done in matt black transitioning into the Prestige maroon.

Our Favorite String

A frequently asked question by our clients at the World Headquarters of Racquet Quest, LLC is “what is your favorite string?”

I am going to tell you what it is, and tell you why it is, and why, I believe, it should be your favorite string as well!

VS Team v VS Team

It should come as no surprise that natural gut is our favorite string!  Well, of course, you say!  It is probably everyones favorite but it is way too expensive for most recreational players!  You are correct that natural gut is everyones “favorite” string, however, you may not be correct about it being too “expensive” for recreational players!

What follows is predicated on the belief that “performance” is the primary factor in selecting a string.

On the positive side:

  • Natural gut plays better longer than any other material.
  • Natural gut is more stable than most string materials.
  • Natural gut is more forgiving (comfort) than most other materials.
  • Natural gut is more eco-friendly than other materials.
  • Natural gut is a good hybrid component.

On the not so positive side:

  • Natural gut is expensive @ $70.00 to $75.00 (installed).
  • Natural gut is more expensive than other materials.
    • Making natural gut string is very labor intensive.
    • Making high quality natural gut is limited to a “few” major manufacturers.
  • Natural gut can be affected by moisture.

And, how do you quantify “plays better”, anyway?  Some players are fine with string that has long since offered any performance!  Some strings have a “play”life of a couple of hours!  So, the player must decide on what is important.

But, if you ask us, natural gut is our favorite string!

Dealing with Options, and What are the Options?

The little video you see above is just a reminder that we do not promote polyester based string for underage players!  So, what is underage?  Oh, under 100 would be a good number, I think!

OK, smart alec what are the options?

  • No Polyester

PEEK/Zyex

Well, there are many, however, if the option is only relative to “no polyester” the best option is PEEK material.  This material is usually referred to by the brand name Zyex which is the fiber division of Victrex of England and known by the Ashaway name as well.  This material is normally found as a monofilament construction as is most polyester materials.

PEEK/Zyex offers exceptional durability and energy!

Multifilament

  • Premium Playability

Natural gut still is the number one playing string available.  We use Babolat and Luxilon natural gut but there are other options like Pacific, Klip, and others.

  • Excellent Playability

Multifilament construction can act as a spring and return both performance, power, and comfort.  Typically the more individual fibers the better.  These fibers are usually bonded with a soft adhesive and show signs of “fraying” during use.

Strings in this category include Tecnifibre, Ashaway, Babolat, Head, Yonex, and Gosen and others.  Expect to pay $42.00 + for these strings installed.

  • Playability

These multifilament strings are typically constructed using fewer larger diameter fibers to enhance durability.  The same “fraying” occurs with this grade of string as well however the larger diameter will last a bit longer usually.

Strings in the category include Tecnifibre, Babolat, Head, Yonex, IsoSpeed, Gamma, and others.  Expect to pay between $35.00 and $40.00 for these strings installed.

Synthetic Gut

  • Value

There are probably 10000 strings that fall under this umbrella!  9999 of these strings will be a nylon core with one or two overwraps bonded to the outer surface.  This material and construction has been around for many, many years and has offered great service to millions of tennis players…and is still in major use today!

Strings in this category include at least one, and probably many more, set from every major brand!  If you are really cost-conscious do not overlook this material. Expect to pay $27.00 to $35.00 for these strings installed.
