In a string does color matter?

Of course color matters!  Brands have made history on color!  Prince Green, Head Orange, Babolat Blue, for racquets but what about string?

Sure, again!  Luxilon Silver, Babolat Black,  Solinco Green, Victrex Putty…what?  Which of these monofilament strings do not have any color pigment?

If you guessed the Victrex you would be correct.  But why not?  The natural color of the polymer is probably the very strongest a string can be, however, without color they would not be at all interesting or recognizable!  The natural Victrex color is typically what we use when evaluating the string because it is visually different.

Victrex does make strings with black-pigment, but this post is about the difference pigmentation can make in a string.  In a previous post some years go we determined that color had very little affect on string properties and this evaluation shows pretty much the same result in a different format.

You can see by this graph there is very little difference between the two Volkl V-Star strings.  In fact it would be safe to say the strings are identical.

We will continue to evaluate strings with pigmentation to determine if any color does exhibit an affect on the properties.

Head Speed Pro Black

As you probably know by now Novak Djokovic plays with a version of the Head Speed but in black, not black and white! So it was only a matter of time until the all-black Speed Pro became available.

Until now we only had the black and white Speed Pro demo but now we have the black one!

This review will include the white and black version of the Speed and we will include a comparison to the Wilson Blade Pro!

These are each extraordinary racquets!  You will discover subtle differences in the specifications, especially the Wilson Blade Pro being a 16×19 pattern and the Head Speed Pro, in this case, is 18×20.  The geometry and frame of the 16×19 and 18×20 are the same so the numbers are meaningful!

Pick Your Prestige!

Racquet Quest specializes in high performance tennis racquets and they don’t get more high performance than the Head Prestige models!

We recognize the attachment players have to racquets so we keep a good supply of Head Prestige racquets of all models and even a year or two of prior models.

Here is what is currently available:

Still Committed to Your Racquet!

For the past few years and certainly the past year Racquet Quest has been committed to tennis racquets and yours is included!

Hopefully the days of the “mask”are over and we can resume actually talking to each other and be understood! Of course if you prefer to wear a mask that is OK, too!

Here is what is not OK!

Not caring about your tennis racquet is not OK, and by that I mean keeping it in the best possible condition. That includes string, grip, grommet sets, overgrips and general reactions of beating it against the ground or net!

We have seen five year old racquets that look brand new and five day old racquets that are in really poor shape! One of the most damaging “strokes” in tennis is the ball pickup stroke! This is not a stroke at all but a way to keep from bending over to pick up balls!

Using the racquet head to scoop up the balls is easy and cool! It is also the quick way to ruin the bumper guard which is there to protect the Racquet from normal stroke, not pick-ups!

So, what do you do about it? The next time you consider scooping up balls with the racquet consider tapping the ball to start it bouncing or simplpy use the fingers on your hand to pick up the ball…that would be good!

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.
