Big 10 Tennis Player of the Week.
Jack Anthrop has been playing extraordinary tennis for a long time and was recently named Big 10 Tennis Player of the Week after an impressive outing in Dallas!
The link below will take you to the Ohio State post; however, I want to share some of the things Jack has done to secure the game he has.
Jack uses a Head Speed SMU racquet. The head size is 96 square inches and has a swing weight of 333 kg/cm^. This inertia couples with the overall weight of 352 grams (12.4 oz) to create stability and power.
Jack uses MonoGut ZX Pro natural at a reference tension of 56 pounds and string bed stiffness of 60 pounds. This creates a dynamic stiffness of 393.6 PPI.
Jack has been using Ashaway MonoGut ZX Pro since the age of 9! Yep, that’s right, age 9! MonoGut ZX and ZX Pro material is PEEK, a unique string that offers outstanding comfort, feel, and power with better durability than some other materials.
It is our position that more players of any level should consider MonoGut ZX or ZX Pro (thinner). It really just makes sense…just ask Jack, Big 10 Men’s Tennis Player of the Week!
Let us know if you have questions about Jack’s racquet or string. We have been working with Jack since age 9, and we would like to share what we can to help achieve your tennis goal(s).
Thank you, Head and Ashaway, for your continued support!

Congratulations, Jack, your new Head Speed SMU’s are on the way.

You need to see this!
For years, we have been exploring the properties of materials that make up many of the tennis strings used by players now.
What we found, over fifteen (15) years ago, was that polyetherether ketone (PEEK) is the best string material for preventing arm, elbow, shoulder, and other injuries while enhancing performance.
What!
We love natural gut and use a lot of it; however, PEEK can take more “abuse” than natural gut, environmentally.
If you are joining the Racquet Quest community, you may be perplexed by this statement. And for good reason. If you are not near the world headquarters of Racquet Quest, LLC, you may have never heard of PEEK, marketed by Ashaway as MonoGut ZX and ZX Pro.
Why?
PEEK is a unique fiber that requires an understanding of its properties, unlike most other materials that do not possess the performance properties of PEEK.
Stringing with PEEK requires caring about the player and the racquet!

String bed stiffness loss…17.7%!

Ask your racquet technician to set up your racquet with this string. We believe you will be glad you did.
Take a Guess?
A very good player and client came into the World Headquarters Wednesday with his three (3) Tecnifibre TF40 315’s wanting to re-string. There is nothing unusual about that except this time he wanted to discuss different strings. So we did!
The final three (3) strings under discussion were:
- Tecnifibre Razor Soft 17 (current string)
- Volkl V-Star 17
- MonoGut ZX Pro 17
The first two are considered to be polyester, however, I am not sure V-Star fits entirely in that category, and PEEK is the material with the MonoGut ZX Pro name. All of the strings are monofilament.
We learned in a previous post “a picture is worth a thousand words”, so we are including a picture to help in our guessing.
Take a Guess?
Here are some basic properties of the subject racquet that may contribute to your guess
- Weight=342
- Swing Weight=327
- RDC Flex=63
- Flex Four Flex=50.8
- Grip Size= 3
We hope you will make a guess in the “comment field” below and if you do you can use the string name or the color…we will figure it out, and thank you for you guess!
Head Auxetic 2 Radical Pro 2025
The Radical Pro represents the pinnacle of a player’s racquet. So, this review is based on our desire to see how much power we can squeeze out of it through string bed stiffness.
The following specifications explain why this racquet’s natural properties make it a powerhouse.
This 98-square-inch racquet packs a powerful 339-gram weight with a very easy-to-handle 331 swing weight!
With this racquet, you will not be pushed around by big hitters.
As tested, this racquet has a stiffness rating of 66, which is moderately high. However, with an effective stiffness of 27.1, it is well within the range of any player who can benefit from the other performance factors.
As you can tell from the picture, the racquet is ORANGE. These pictures are the skills of Bobby Diviliansky, a high school student who just happened to stop at the World Headquarters! His brother Ryan is a client, so he had a reason to be here.
