Head Extreme Team 2024
The Head Extreme Team 2024 is the lightest of the Extreme 2024 Series and presents a 105 square head with a 16×19 string pattern…which means a very “open” string pattern! This “openness” can contribute to spin.

The “openness” can also contribute to lower string bed stiffness and may return a little more energy to your shots
This racquet makes a perfect platform for customization if your game changes but staying with a 105-head size is important.

Is this Extreme or what!
The new Head extreme series is here and it will not be ignored! The citrus green color will make sure of that!
Head Extreme MP 2024
The Extreme series has been a very good one for us and our players and we believe this series will be even better!
Why?
This Extreme capitalizes on the big market for 100 square inch racquets but adds some performance advantages like a firm flex with proper flexibility in the shaft, a great grommet system with very deep and protective sections for the string.
As you will see in the data this Extreme carries a lot of power to the court for you, and the string bed, with a dense center, can be adjusted to suit your game with out becoming too stiff.
The Extreme Series consists of:
The Extreme Pro 2024 98 square inch head and slightly heavier, slightly more flex, and a slightly lower swing weight.
The Extreme MP 2024 which is this review.
The Extreme Team 2024 which is a 105 square inch head indwell reviewed soon.
And my favorite the Extreme MPL 2024! This is a 100 square inch head and a perfect weight to allow for customization to your specifications! This will be reviewed soon!

Monofilament Material Comparison
Most monofilament tennis strings are polyester, a blend of polyester, or PEEK.
As you know, we believe there is no wrong string, just wrong applications. The graph will show the comparative stiffness of three (3) materials. The string is pulled at a rate of 1mm per second. The resultant spreadsheet for this particular test is about 5300 rows long.
With our spreadsheet, we have access to every mm of data. Maybe sometime we can post some of the individual data points.
Blast is polyester, V-Star is a unique blend of material (I do not know what it is), and MonogutZX is PEEK (polyetheretherketone).
The graph shows the cycle from 0 to 50 pounds three (3) times, then to failure (UTS). The quicker (shorter distance) the string reaches the 50-pound mark, the stiffer it is. MonoGut ZX did not fail in the 180mm excursion. You can see, in this case, the stiffer string fails at a higher force but shorter excursion.
Stiffer strings deliver less power and have a higher shock value. The midrange stiffness shows exactly what would be expected, and the softest string also indicates expected results.
Let’s get up to Speed!
The new Head Speed 2024 series is here! This series comprises the Pro, the MP, the MPL, and the Team.
The 2024 Speed series retains the white and black graphics pack, however, the finish “feels” different. Don’t worry! It is not the finish that falls off or turns to sticky stuff!
We will start with the MP, for no reason, except it is the one I picked up!
Head Speed 2024 Series
From our perspective, the Speed series is the most popular of all the Head series but not by a huge margin!
We believe this is a factor of proper stiffness and powerful head geometry.
As you read the numerical reviews this will become clear.
The first clue that this is going to be a powerhouse is the swing weight of 343! This property reminds me of many years ago when car dealers would use their most powerful cars for demonstration purposes! Very impressive!
Sort of the same principle applies here being that heavier racquets will perform much better than light racquets, however, 343 is a little more than we would recommend for most players. We will update this property as we setup more Speed MP 2024’s!
