Head Squared
We have demo racquets of the new Head Squared racquet. The racquets will arrive soon, and those who have tried it agree it is quite a different racquet!
The racquet specifications make this a model that will suit players of many abilities, and is a stable and easy racquet to play with!
You can demo your Head Squared now at Racquet Quest for delivery about mid-April!

Because this racquet is so different, we have done a few “customizations”. This post will include two (2) of those customizations. After you take a look at this data, we can discuss what players thought of each.

The Racquet Quest World Headquarters will be closed on Monday, March 30, so I can get my eyes fixed!
Thank you!

Weight is your Friend!
At Racquet Quest, we deal with numbers and discuss racquet properties in terms of them. So what is a better-known number than “weight”?
In the video, we concentrate on swing weight. Please take a look at the video here or on YouTube and let us know if you have any questions.
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!
