Head Graphene 360+ Prestige Pro

So, what’s in a name?  In the case of the name “Pro” it is weight!  Right out of the box this racquet is ready to go with a wonderful weight and swing weight that you will see in the specifications.

The Prestige Pro is the “different” Prestige in the series with a more sculpted geometry.  This is most noticeable in the shaft right above the grip with tapers and contours all the way to the throat.  The head geometry is more elliptical in cross section than the flat section used in other Prestige racquets.

As you look at other Prestige racquets the difference in the cross section is noticable.  The Tour for example has a “flat” beam cross section and the shaft right above the grip is also a “flat” cross section with little very little “sculpting

The Prestige Pro is a racquet anyone can use with a nice 16 x 19 string pattern and reasonable stiffness.

This is a legitimate 95 square inch racquet with a 16 x 19 string pattern that suits most players.  The full Prestige “cap system” adds a nice measure of stability along with swing weight that gets this racquet into the “power and control” category.

Head Graphene 360+ Prestige Tour

When we do the testing and “number taking” for our demo racquets, we try to think as the consumer may think and include comments that may help the consumer make the best decision.

We do not want to make these posts so dull that you go to sleep, but data is essential, so we are going to include it…so stay awake!

Data is particularly relevant to the Prestige Series from Head.

This review is for the Prestige Tour, and it points to the differences between Prestige racquets that may go unnoticed or misunderstood.

The Prestige Tour is a 99 (645 cm²)square inch racquet with an 18 x 19 string pattern. If you have read the post on the Prestige MP, you may wonder, what’s the difference?

You may notice that the Prestige Tour has one (1) fewer cross string. Not a big deal. You may see that the Prestige Tour has one (1) square inch larger head size. Also, not a big deal. What you may not notice is the Prestige Tour has an in-plane stiffness of 400, and the Prestige MP has an in-plane stiffness of 359. That is a big deal! Even with a bigger head and fewer strings, the Prestige Tour has a higher string bed stiffness than the Prestige MP. The higher the in-plane stiffness, the less the racquet will “bend” during impact.

The Prestige Tour is more stiff overall (62 v 58) than the Prestige MP, and the 21.5mm beam contributes to that stiffness.

So, take a look at the numbers for this racquet to see if you can find other exciting differences!

Head Graphene 360+ Prestige MP

We are finally getting the time to work on these marvelous new racquets from Head! In this case, it is the Head Graphene 360+ Prestige MP.

The Prestige is a fascinating series for Head, but I think it is often overlooked when considering a new racquet purchase. I believe the “performance” category excludes a lot of players that could very well use this racquet if it is appropriately set up. Secondly, I think players have the mistaken feeling that the Prestige series is too stiff!

I believe you will see by the following specifications that neither are necessarily true!

The Prestige series is, in my opinion, the best looking new racquet in a long time. However, in a performance racquet, what does “looks” have to do with it? In my opinion, a lot!

This racquet is the “true” 98 square inch (630 cm²) head size with an 18 x 20 string pattern and, of course, the excellent “cap system” that contributes to the performance of this racquet. You will see in the specifications that the swing weight is on the “light” side, allowing for customization to suit any player.

Head is now including a CPI, “Control Power Index,” and this racquet ranks as a CPI 200 compared to the Prestige Pro at CPI 300. The difference is a function of the tight string pattern and flex. The thin 20mm beam throughout contributes to the nice flex of RDC 58 after stringing.

A lower CPI indicates to us that the racquet will do no more than you ask of it! If you want the ball to go fast you swing harder! The racquet will not force to to “fear” your stroke!

If you are considering an 18 x 20 string pattern this racquet should be right at the top of the list.

Our COF numbers are quite good which indicate a positive contribution to “spin” considering the tight string pattern.

String. What is important?

The essential function of string in your tennis racquet is to return energy to the ball as it collides with the racquet. It is evident that if there is no string or a broken one, the racquet can not do what it is intended to do, and your shot is going nowhere or worse, everywhere!

There are about thirty (30) string brands, and each brand has about ten (10) different models, and maybe three (3) different colors, so there are nine hundred (900) possible selections! Nine hundred is way too many strings!

You and we need to consolidate string data so we can make the right decision for you, your playing style, and your physical capabilities.

We test every string for elongation, creep, (stability), with a little bit of elasticity data observed. This testing returns our exclusive Power Potential© for each string, and that is the basis of our decision-making process. Naturally, the higher the elongation, the more power the string will return to the ball, and conversely, the lower the power potential, the less power that “can” be generated. You can observe this fundamental by dropping a tennis ball on a concrete floor and then on a strung tennis racquet from the same drop height and see which one bounces the highest.

I use “can” because power, to a great extent, comes from how hard you swing the racquet, which, of course, brings the prospect of overdoing it and subsequent injury! A low power string demands a more powerful swing that involves the entire arm, hips, and legs.

Low power, in the form of a stiff string, has been associated with control, therefore, the increased use of stiff strings. However, with stiffness comes another downside, and that is stability. Stiff strings typically lose tension quickly and need to be changed frequently. So here is the real problem; the string may not be broken, but it is not playing well at all. There is a difference between durability and performance! If your goal is long term performance, a stiff string is not the answer.

What, then, is the answer?

Choose a string with an elongation of 10% or higher! Oh, great! You say. How am I going to know that!

Well, beginning January 1, 2020, I will be posting the power potential of every string we have tested over the years! There are over 500 items on the current list sorted by brand. The color coding is RED if 5% or less, GREEN if 10% or higher, and BLUE for everything else. Note, however, that natural gut is included in this data and will probably not reach the 10% Power Potential© threshold, but is still the best performance string available.  This is due to the dynamic properties of the natural fibers, so, until there is a separate classification gut will be included as is.

A previous post, “What is Soft?” goes into graphical detail.

As new strings are added, some older ones may be deleted because they are no longer manufactured. However, some very old ones may remain due to their “legacy” status. This chart is a preliminary format but will get us map toward the right decision!

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.
