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.

The Racquet Quest Podcast…update!

Thank you for listening to the Racquet Quest Podcast!

I am posting here to make an addition and a correction to a previous podcast, and this is quicker than waiting for a week or so for a new episode.

The “Stringing and Racquet Data” podcast was cut short, so I will finish it here. 

We were talking about the three (3) scale system we use to determine the torsional balance. The racquet is weighed at the midpoint of the head at the “top” and “down,” and the butt cap is resting on the third scale, and that is called the “butt.”

I don’t recall the podcast numbers right off, so I will use numbers from another racquet to explain. The racquet is a Wilson Ultra 100. The “top” weight is 95.3 grams, the “down” weight is 96.0 grams, and the “butt” is 119.9 grams for a total of 311.2 grams (10.97 oz.). So you can see the difference between the “top” and “down” number is only .7 grams, which is about a quarter of the weight of a vibration damper!

However, if this number was over 5 grams, we may want to “match” the numbers a little more closely! But, what if we wanted to increase the “top” weight by a lot to have the head heavier on one side than the other side? Why? Maybe a “training” aid to remind the player to keep the head lower, for example. Our experience shows that a difference between the “top” and “down” of 6 grams is noticeable.


On the Yonex VCore Pro 97 – Racquet Review, I noticed after the fact that I had indicated the Ereca System calculated the balance (CG) to within one-tenth of a centimeter! That would be pretty good, but in fact, the Ereca System calculates to within a tenth of a millimeter! Very precise! As of now, the Ereca System does not calculate swing weight as I tried to correct on the podcast but wanted to confirm that point.
