Consistency. What Does It Look Like?
Consistency is a component of almost every successful thing we do each day!
But, what does it look like? Well since this is a tennis centric post it will look like this:
What you are looking at is identical racquets, identical string, identical failure location!
If you find the very end of each string you will see how consistent this failure location is.
This string is a high elongation material so will notice that the ends of the broken strings are very far apart.
This is a good thing since it (elongation) contributes to comfort and power when hitting the ball.
This failure location indicates the player is striking the ball with consistency! That many explain the UTR of 13.3!
What else does this failure location show us?
- Most impacts are not in the center of the racquet.
- The string spacing in this area is a little more “open” which may “catch” the ball and contribute to rotation.
- There are more strings for the ball to “roll” over before leaving the racquet which may contribute to rotation.
Consistency is important in everything we do. Visualize it like the string bed of this racquet and try to hit the same spot each time you do something…anything!
Be Prepared!
Be Prepared!
It sure sounds simple but is it? Not really! When talking about tennis preparedness that means having enough racquets ready for the tournament, organizing training sessions, plenty of shirts, shoes, and socks, of course!
But, what’s missing?
Your string is missing! Sure, you have done a great job of getting your racquets ready but I don’t see several sets of the string you use in the bag! Why not? You may believe they will have it at the tournament site, and, if you are using a commodity string, you may be right!
But what if you’re using a high performance string that is set up for your playing style?
- Take a few sets of your preferred string with you. I prefer sets over reels but that is up to you.
- Tell the stringer exactly what you want. That means knowing what you want so be prepared!
- Request that your racquet be strung using two (2) pieces of string and the cross strings be started at the top of the racquet. No exceptions! No ATW’s, No natural one-piece, simply two pieces top to bottom!
Know how to identify the correct stringing procedure and don’t accept anything that is not up to your standards!
Most qualified stingers will appreciate your input and do the proper job for you!
Today a racquet came in that was strung at a tournament that missed the mark! One-piece ATW, sloppy knots, distorted head shape, and a string that is not used by the player!
That is why we are posting this… “Be Prepared”
Head Extreme Tour
Head is, I believe, going to expose and promote the Extreme Series to a greater extent than before.
Why do I think that? Because I am holding in my very own hands a Head Extreme Tour! This 98 square inch racquet continues the Graphene 360+ technology which has become popular in the last several releases of Head Racquets!
The new Extreme series will be shipping in July so we can’t show many pictures except the all-black version I am holding.

Head Extreme Tour
The other Extreme models will be:
Extreme MP – 100 square inch head size, 300 gram
Extreme S – 105 square inch head size, 275 gram
Extreme Lite – 105 square inch head, 265 gram
Extreme PWR – 115 square inch head, 230 gram
Extreme Jr – 100 square inch head, 240 gram
All of this series continues the “extreme” optic yellow colorway but it is now complemented by a really nice grey upper shaft and hoop! The optic yellow grip may be over the top but that is easily changed.
The Extreme Tour is fitted with a TK82S grip pallet for a comfortable rounder feeling.

Racquets Taking Off …and Racquets Crashing!
Sometimes I am surprised at how a tennis racquet will find a new life after a few years of dormancy! And of course, I am astonished at how some racquets are “finished” way before their time!
The new Head Graphene 360+ Prestige is an excellent example of a racquet taking off, and the Head Adaptive Speed is an excellent example of a racquet that was laid to rest prematurely, in my opinion!

Head Graphene 360+ Prestige
Let’s start with the Prestige. One look says this is a racquet you want!
You may not care that this series has been a mainstay on the pro tour for over 25 years! You may not care that this racquet has a unique feel or a magnificent “cap” system.
You may not care that this racquet comes in a model to suit almost any playing style! NO…you care about the way it looks! The rest of the good stuff is just icing on the cake or racquet in this case!
Other racquets that would fit this category are the Wilson Pro Staff and Yonex VCore series.
On the other hand, a racquet that met its demise way too soon is the Head Adaptive Series! If you don’t know much about this series, it is not your fault! It was pulled way before it’s time.

Head Speed Adaptive Tuning Model
The Adaptive series was just that, adaptive! The string pattern could be either 16×16 or 16×19. The length could be increased in increments of .20 inch up to a total length of 27.6 inches (701mm).
Plus, the swing weight can be increased by using the optional heavy side grommet set, and the overall weight can be increase by inserting the “heavy” butt cap!
So, what happened? I think it was just too hard to sell for those places that don’t have hands-on expertise or didn’t want to take the time to explain the benefits of this concept!
Because the grip pallet was designed to be removed, it is likely that, if not done correctly, there would be some squeaking. That is not good, but it is not a problem that should keep a great idea from being a great racquet!
We still believe this is a good idea and if you do too, and want to take a look at this great idea, we have some in stock!
Head Graphene 360+ Speed PWR
I suppose you have a pretty good idea what PWR means, right? Well, you would be correct! The Head Graphene 360+ Speed PWR is just that at a calculated power value of 2297.5! Compare that to the calculated power value for the Head Graphene 360+ Speed Lite of 1838.3! Twenty percent (20%) more powerful than the Lite!
This is what a 115 square inch head size can do for a racquet! The strings are quite a bit longer and more widely spaced which contributes to power, and comfort.
This head size is normally referred to as a “game improvement” racquet and relegated to those players that were not too athletic and/or didn’t want to exert too much energy on each stroke. In other words slow and short swings.
I am not sure that is the case with this racquet! Sure it has a big head and a thick beam but it sure does feel good when picked up (first moment)!
If we were going to recommend this racquet I would suggest some weight added to the rear end. The head does not need any additional weight.
