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.

Head Graphene 360+ Speed Lite

As you probably guessed, this is the lightest of the Speed Series, 100 square inch head size, at a weight of 281 grams (9.91 ounces)!

There are several positive features in this racquet and one is the reasonable flex (stiffness) of 63 RDC, plus the uniform string pattern that provides a consistent hitting experience needed by developing players.  This pattern should contribute to extended string life as well.

Head Graphene 360+ Speed Lite

As with all light racquets, this one can be customized as the need or desire arises, and I think that will happen more quickly than most other racquets.

This is just too light, in my opinion, for players wanting to improve all aspects of their game.  Remember, weight is your friend!  However, if you prefer a light racquet for any reason this is a top choice!

Head Graphene 360+ Speed S

I think we all know what “Pro and MP” mean but what about “S”?  I am not sure, so we are going to call it “Special”!

The Speed S is indeed special and probably one of the best all-around racquets for 2020!  You will see by the specs why this may be the case but a couple of things stand out.  A 100 square inch head size.  A uniform 16×19 string pattern and 25mm beam producing the stiffness of RDC 64!

The overall weight and swing weight are just right for most advancing players and can be modified when the need arises!  This is really a “players” racquet in disguise!
