Head Prestige Pro 2021
This years Head Prestige Pro is last years Prestige MP. This name change was made to synchronize all the 18×20 string patterns as the “Pro” model…I think!
So, what’s in a name? A thin beam, heavy (sort of), 18×20 pattern, players racquet, that’s what! The Prestige Pro also includes the new Auxetic material and construction for a refined feel.
For some reason Head Prestige racquets have been called “stiff” by some and this is certainly not the case and never has been. This racquet is not stiff! As with any racquet the string selection can have a huge effect on “stiffness” so take a look at the effective stiffness!
I believe this is going to be a “control freaks” racquet! This racquet could also be a baseliners dream come true. The weight will drive through the ball and the swing weight will allow for some last nano-second stroke adjustments.
Take at look at the data below then go to the Prestige 2021 Comparative Data post to see all the models in one place.

Head Prestige 2021 Series Comparative Data
Jumping back and forth between reviews and data is not fun nor is it efficient so we have been posting comparative data. Now all the important stuff is in one place.
All of the data is based on a “play ready” racquet. That means an overgrip and vibration damper, and unless otherwise noted…string!
As you are looking at the data try to determine which numbers mean the most to you and how you could use them. For example, the Pro has an overall weight of 342 with a swing weight 318. How does that compare to the MP?
Keep in mind that weight and swing weight can increased but not easily decreased. No, making the racquet more “head light” statically does not reduce the swing weight as recorded on testing devices that grab the racquet 10cm from the end! That is why static balance (CG) should not be used as a performance metric.

Head Prestige MP 2021 Series
OK, here comes another racquet review!
You know our reviews are “numbers” based, not hitter based because we just like numbers! Hitters are Important but to get the most meaningful data from a racquet requires numbers. These numbers can then be applied to the feedback of the hitter.
The new Head Prestige MP 2021 is a 99 square inch head with the 18×19 string pattern so common in player style racquets. This combination may “scare off” some users but that would be a mistake in our opinion.
As you would expect this racquet is a thin box beam box design which creates an in plane stiffness of 384.6 pounds, which can be used to create a very friendly string bed stiffness. Take a look at the “effective stiffness” and you will see what we mean!
In addition to the nice in plane stiffness this racquet uses Head’s new Auxetic construction in the throat which is designed for comfort and control from each hit by allowing the throat to “expand 
and contract” a little.
The bright red color of last years Prestige series has been replaced with a “matt” graphite transitioning into the classic Prestige maroon aroun
d the head of the racquet making this a classic in its own right!

And the winner is…Head FXP 17
Head FXP is a string that seems to be largely overlooked and I am surprised after seeing the results of the installation and testing!
| String Name | Category | Gauge | Ultimate Tensile Strength/Lbs | Knot Strength/Lbs | Country of Origin |
|---|---|---|---|---|---|
| Head FXP | Multifilament - Nylon | 17 | 165.9 | 93.4 | Japan |
Both the tensile strength and knot strength are exceptional and the graph shows that this string is very “elastic” which is a good thing for tennis racquet string but sometimes just not considered.
Head FXP 17
The area under the solid red lines is considered a stress-strain curve and indicates the “elasticity” of string by how close the lines fit from 0 to 50 three (3) times. A perfectly elastic material would be one line even though it went through three (3) cycles. What you see here is quite good and one of the reasons it is the winner!
And the winner is…overview
Racquet Quest is going to add a “winner” of the week to our website as a way to develop a fun way to look at string!
Each week we will select a string that has exhibited outstanding properties from one of five (5) major categories:
-
- Synthetic Gut
- Mulit-filamanet
Nylon
PEEK - Natural gut
- PEEK Monofilament
- Polyester Monofilament
The winning string must have been installed in the most recent week either in a client or demo racquet.
We will include as much information as possible including graphs and the country of origin.
We will try to post “And the Winner is…” on Friday so take look!
