Head Graphene 360 + Gravity MP Lite
The Gravity MP Lite as you would expect is lighter than the MP by about a ½ ounce with a corresponding reduction in swing weight. This can be easily remedied by increasing the swing weight while not effecting the ovefrall weight very much.
The MP LIte is a great example of a “customizable” racquet and deserves great consideration by any player seeking a performance racquet that will stay with them for a long time.
The head size of 100 square inches is consistent with the Pro and MP models.

These are not the same racquet but the entire series uses the two color graphics package with Lava on one side and Miami Green (my words) on the other. Sort of a fun point!
Take a look at the specifications that follow.

Head Graphene 360 + Gravity MP
The new Head Gravity MP seemed like the perfect place to start with this new series of racquets so that is what we did!
We believe this racquet falls between the Prestige and Radical series and will appeal to more players than either of those. Plus, there are two (2) 104 square inch models, the Lite, and S. These are relativley “thin” beam, (Lite and S = 24.4mm) racquets that Head has been missing, in my opinion, for a while.
It has a “flip” color scheme…one side is lava and the other is Miami Green (my word).
Head Graphene 360 + Gravity MP Lava Side
The head shape is a little more round. The weight is 312 grams (11.01 oz) which I think is a little light. The swing weight is 324 kg/cm² ( a good starting point).
The unique fiber layup is designed to “uncoil” at impact contributing to a new kind of power, and hopefully comfort.

The Series consists of a “Pro”, “MP”. “MP Lite”, “S”, and”Lite”. There is a Model Comparison post where you can see all of the racquets in one place.

New Head Graphene 360 Radical! Here Now!
The new Head Graphene 360 Radical has arrived and I have already chosen the one for me!
The four (4) racquets in this series cover every possible player style and the new graphics package will appeal to most players. This is a win-win Radical Series!
Head Graphene 360 Radical Series
Just in case you are wondering which one I have chosen it is the Radical S! Why? I handle a lot of racquets each day and this racquet just “feels” good when I pick it up! Plus the 102 square inch head size fits me fine.
This series is the most impressive Radical Series I have seen in a few years.
You can read the reviews of each of these racquets on this site but you really should come by and take a look and “feel” for yourself.
My setup is going to be this racquet strung with PEEK at 52 pounds. I am going to increase the weight to 315 grams and the swing weight to 315 kg/cm² as well.
I am anxious to start playing again and this is just the racquet to motivate me! Motivate yourself, too! Get one!
This is a comparison sheet of the four (4) models so you can get some idea as to which racquet may suit you!
Head Graphene 360 Radical Series Strung
The Rebel Backpack and Radical 6 Racquet Combi add to the excitment of the new Radical racquets! Complete the package with these bags!
Head Graphene 360 Radical PWR
As you would expect “PWR” means power! With a calculated power factor of 2294.7 that is true! You can see by the picture above that the PWR has a slightly larger head size (109.9 square inch) and a reasonable beam of 26/25/23 which contributes to a racquet stiffness of 65.
Head Graphene 360 Radical PWR
Unique to the PWR series of Head racquets this racquet can be either a 16 x 19 or 14 x 19 string pattern by replacing the top grommets with the included grommet set.
This format creates a “fan pattern” that makes the upper portion of the string bed very “open”.
This is a picture of last yesrs model. Whichever pattern you choose you will be presented with plenty of power…PWR!

Head Graphene 360 Radical S
As you can see by the picture above the Graphene 360 Radical S looks a lot like the others in this series, however, the “S” stands for “special”. Why? Because the “S” combines the most popular specifications from full blown players racquets and brings them to the masses! In fact, according to Head, this is the best selling Radical!
Head Graphene 360 Radical S
The 102 square inch head and stiffness of 59 are fitted into a thinner beam (22/25/23) to create a very user friendly combination.
