What’s New?

We have had a “sneak peek” at some new tennis racquet models that will be arriving early in 2021!  Typically, we can’t divulge a lot of the details yet but suffice it to say these are exciting models!

But let’s back up a minute and talk about new racquets that are here, or should be here, or will be here soon!  The new Wilson Pro Staff series had a delivery date of September 28, 2020.  They are way behind!  If you are waiting for a new Pro Staff…we are sorry!  Who knows what happened, but it is not good when the expected deliveries are not met!

Do you think that Wilson going “direct” has anything to do with this shipping delay?

The new Pro Staff RF 97 Autograph will change only to the Pro Staff colors of red and yellow stripes; the Pro Staff RF 97 will get a new grip pallet and butt cap setup that is intended to be easier on the hand.

The new Tecnifibre RS Series offers some interesting geometric concepts that continue their push for more player traction.

The new Head Graphene 360+ Radical Series retains the classic Radical Orange, but this one is “in your face orange”!  Awesome!  A cool gray shaft and grip temper this orange!

The Radical MP that we have seen has a few changes in shape and dimensions, and in fact, it is a different racquet than the past years.  The head shape is more “round” by a slight amount, and the beam cross-section is different.  The beam height is slightly less than the previous version, but the stiffness remains nearly the same.  The shape of the “yoke” section is a little deeper and slightly wider at the junction of the head.

The new Radical has a “slicker” aerodynamic grommet system, for, no doubt, greater head speed to go with the “spin” friendly grommets!

And, the Radical Series has been scaled back to three (3) models!  The Radical Pro, the Radical MP, and the Radical S.  The Radical S is 102 square inches and the Pro and MP are 98 square inches.

The Head Graphene 360+Gravity has been a top seller and therefore is only getting a “cosmetic” make-over!  The Hot Lava and Teal are being replaced by very interesting blue and yellow graphics!  They look really good!

The Head Graphene 360+ Speed is staying the same but will add a black edition to the mix!  It seems Novak likes black better than black and white so there will be a “black”  in early 2021!

Don’t forget the Head Instinct “Effortless Power” series!  It continues in a new color scheme, still blue and blue but in a more Head consistent pattern.

This week we will be getting the new demo racquets setup for your evaluation…if all goes well!

It is reassuring to know even in this time of uncertainty that racquet companies continue to produce great products that can, and will, help many players stay in the game!

We believe this is an exciting step forward in specialized tennis racquets and preparation.

We are anxious to hear your thoughts on this move to better racquets for everyone…especially you!

 

Head Graphene 360+ Gravity MP/Tecnifibre RPX

Normally our racquet reviews are when a racquet is brand new; however, this is a case where the updated string, RPX, from Tecnifibre is an excellent opportunity to add another review to the site!

There are some excellent reasons to review the same racquet again with different string or tension settings.

  •  It allows us to evaluate new strings for comparison purposes.
  •  It will enable the player to demo the same Racquet with a different string.
  • The string can affect the overall weight to a small degree but significantly impact swing weight.

For example, this racquet with Victrex 7718 PEEK string (15.9grams installed) has a swing weight of 318. With the new Tecnifibre RPX (18.0 grams installed), the swing weight is 325. That is not huge, but it is different.

Lead tape, commonly used to increase swing weight, weighs in at 2.8 grams for 12 inches! So, slightly over 2 grams of additional string weight in the strung area contribute to the difference between these strings.

Of course, this also means that swing weight can be reduced, somewhat, by using lighter string! We weigh all of the string we test for Power Potential, so we know which string can benefit either swing weight preference.

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!

Head Graphene 360+ Gravity Tour

Head is adding another racquet to the very popular Gravity Series!  This racquet is the Gravity Tour and in a nutshell, is a lighter version of the Gravity Pro.  Both are 18 x 20 string patterns and, the Gravity Tour is a 22mm beam as opposed to a 20mm beam for the Gravity Pro.

Head Graphene 360+ Gravity Tour

You would think the 22mm beam would be stiffer (power?) than the Gravity Pro, but in this case the extra weight of the Gravity Pro makes it a little more power forward. Our tests show the RDC stiffnesses to be the same (60), and the FlexFour shows the Gravity Tour slightly stiffer in the shaft, 51 as opposed to 46 for the Gravity Pro.

From a numbers standpoint this racquet (14 grams lighter) will fit a player wanting a little more maneuverable racquet but not as powerful as the Gravity Pro. ← Click on this link to see the review.

This review is of a “play ready” racquet.  That is an over grip, and vibration damper.   These accoutrements do contribute to weight and swing weight to a minor degree.
