Head Graphene 360 Radical PWR

Head Graphene 360 Radical Series

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

Head PWR 14 x 19 String Pattern

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

Head Graphene 360 Radical Series

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.

Take a look at the specs below.

Head Graphene 360 Radical Pro

Head Graphene 360 Radical Series

Don’t let the word “Pro” scare you away from trying this racquet! You can see all the specs below but this 98 square inch head and thin beam (20/23/21) add up to a definitive “players” racquet just slightly heavier than the MP but having the same swing weight.

The Graphene material has been re-arranged a little and is now “360” as oppossed to “Touch”. It seems the word “touch” diminished the famous feed-back of the racquet…so goodbye!

Like the “MP” the “Pro” has a slightly more “round” grip shape on a pallet that accepts the Head Sensor, as do all the recent Head racquets.

Wilson Clash 100

Once in a while words “fit”! Clash fits this new Wilson racquet because it disrupts the trend of “everything stiff”. Luckily this trend is dying and Wilson has, in my view, done a masterful job of expediting that demise with this concept.

Wilson Clash 100

Not only does this racquet look good it just feels good in the hand. It is light, maybe too light, but the brain detects something different about this racquet. We all know racquets are all about “the brain”!

In this review you may notice the addition of a couple of specifications. One is “Racquet – In Plane Stiffness”. This is the racquets resistance to”squeezing the sides together. The higher the number the more resistant (stiffer) the racquet is. Another addition to the review is the three (3) weights taken at the sides of the head and at the very bottom (butt cap) of the racquet. This very helpful when matching or customizing a racquet. so I thought we would include it.

Before this racquet is strung it has a noticeable “softness” which is expected given the 52 stiffness (Wilson is not using the defacto device, RDC, for their stiffness rating). However, after stringing, the racquet takes on a different “feel”. It is like the string is pulling all the material components together! I intend to hit with this racquet tomorrow so as right now I have no idea how it will feel.

To get the maximum from this racquet our demo is strung with Luxilon Natural Gut, 125 and the new Wilson Sensation Plus multi-filament with a “wear” wrap. This should be a great setup, so if you want to hit with the latest technology this is it!

For each racquet we do an “Accuracy Index”. This tells us how accurately the ball will come off the string bed when hit at different locations on the string bed. This racquet has an index of 97, which is very good, in the areas of the string bed that show the most failure (breakage). The overall string bed index of 94 is quite good and tells us that the string bed should produce as much accuracy as the players skill allows!

Take look at the following specifications to see if you agree with the player evaluations you may have read.
