2020 is Coming Into Focus!

2019 came and went in a blur!  In a few days it will 2020 and with it will come some exciting new tennis stuff, for sure!

I am not so good at predicting things but I do it anyway!  Here are a few predictions I will make for 2020:

  1. Tennis racquets will become more expensive, but only slightly.
  2. On-line sales of tennis racquets will increase.  See this previous post.
  3. Customer satisfaction with on-line sales will decrease.
  4. Small specialty tennis shops will be the source of information, then #2, and then #3.
  5. Players will stick with a racquet longer, making customizations as needed.
  6. String and stringing will become a more important component of a racquet purchase.  See below!
  7. Tennis related injuries will continue to be a problem for the sport going forward.

    No Underage Polyester, Please!

    Thank you for thinking about the “long term” for all tennis players!

    There are no bad strings just bad applications!

    The right equipment is crucial to the long term enjoyment, and winning, of tennis!

    The local representatives I deal with are committed to our “well being” even though some may feel like they are facing “extinction”!

    An excellent example of what we are talking about just walked in! Two (2) new racquets so poorly strung it is shocking!

    The customer is having serious arm issues with an excellent racquet, with a terrible string setup! But the string setup is probably considered by many to be the ultimate combination, that is RPM Blast in the main and VS Touch in the cross! That combination is coming out in a few minutes!  No more polyester!

    The quality of the stringing is what is so wrong! Had you or I received this racquet, we would have returned it at once! Why? Because it exemplifies the attitude of so many stringers that is “who cares”!

Happy New Year!

Jack Wins at Eddie Herr International!

Congratulations to Jack Anthrop for winning the Boy’s 16 Singles at the Eddie Herr International Tournament!

Those who know Jack know that he has made steady progress on his quest to become a really great player!

However, here are some things you may not know:

Racquet:  Head Graphene Touch Prestige Mid (93) 16×19 string pattern.

String: Pre-production Zyex monofilament, 16L gauge.  Prior to this was Ashaway MonoGut ZX. Jack has been using Zyex (PEEK) material for well over six (6) years!

Tension:  56 (25.4kg)

In addition to Jack’s tennis skills he is also highly proficient at cutting and removing string from racquets!

Congratulations, Jack!

Play Like a Girl!

Yes, I mean it!

Keep reading to see why I suggest you “play like a girl.”

About a year ago, a little girl, Meera, about 12 years old, came into the World Headquarters to demo a few racquets.  She was committed to getting better and wanted a racquet that would help her.

After a few demos, she selected the Head Graphene Touch Radical Pro.  During the discussion of how we were going to set up these new racquets, I mentioned the Head Pro Cap System that is compatible with this model.

If you are not familiar with the “cap” system, it is the plastic parts that fit over the head of the racquet to protect the string.  All racquets have a grommet set, but the “cap” system encloses the string as it is installed therefore is more substantial than the standard grommet set.  The racquet on the left has the “cap” system.

Head Pro Cap System

She purchased two (2) Head Graphene Touch Radical Pro, one with and one without the cap system.

So, other than doing a great job of protecting string it also provides additional inertia, or momentum, that blasts the racquet through the incoming tennis ball!

This momentum creates stability, and a stable racquet will be more powerful and controllable!

But wait, what about all that additional weight?  That is the question we hear anytime we suggest adding weight to a racquet.

Weight is your friend!  Every player is different so matching the racquet to the physical capabilities is critical!

It was so much of a friend to Meera that she quickly came in to have the second Head Graphene Touch Radical Pro fitted with the “cap” system and both racquets fitted with a Head Leather grip!  The leather grip adds about 10 grams to the rear end of the racquet.

So, what are the specifications of this racquet that is being used successfully by a 12-year-old girl?

Take a look at these then tell me you can’t use a “heavier” racquet:

Weight:                               360 grams   (12.7 ounces)

SwingWeight:                    344 Kg/cm² (12.1 ounces)

Points Head Light:            8.03…yes, still very much headlight!

Torsional Stability:            22…very good!

Power:                                2216.6

Recoil Weight:                   176.9

Twist Weight:                    246.9

*Ereca End Weight:          153.0

*Ereca Tip Weight:           207.0

*Ereca is a French company that designs and manufactures racquet diagnostic equipment.

Head Graphene 360 Radical PWR

Head Graphene 360 Radical Series

As you would expect “PWR” means power! With a calculated power factor of 2294.7 that is true! You can see by the picture above that the PWR has a slightly larger head size (109.9 square inch) and a reasonable beam of 26/25/23 which contributes to a racquet stiffness of 65.

Head Graphene 360 Radical PWR

Head PWR 14 x 19 String Pattern

Unique to the PWR series of Head racquets this racquet can be either a 16 x 19 or 14 x 19 string pattern by replacing the top grommets with the included grommet set.

This format creates a “fan pattern” that makes the upper portion of the string bed very “open”.









This is a picture of last yesrs model. Whichever pattern you choose you will be presented with plenty of power…PWR!

Head Graphene 360 Radical S

Head Graphene 360 Radical Series

As you can see by the picture above the Graphene 360 Radical S looks a lot like the others in this series, however, the “S” stands for “special”. Why? Because the “S” combines the most popular specifications from full blown players racquets and brings them to the masses! In fact, according to Head, this is the best selling Radical!

Head Graphene 360 Radical S

The 102 square inch head and stiffness of 59 are fitted into a thinner beam (22/25/23) to create a very user friendly combination.
