Right here…Right now! Squared

The brand new Head Squared racquets are here, but we don’t expect them to be here long!  This is a much-anticipated arrival, and we are excited to show and talk about this racquet.

Head Squared…Here!

In a “nutshell,” this racquet departs from some norms.  That is the Dual Tube foam-filled addition to the shaft, enhancing comfort and calmness.
A 16 x 18 string pattern that offers easy access to deep ball contact.
The overall weight is ideal for aggressive, stable play, and the swing weight makes it easy to handle… and fun!
You can see all the technical stuff in the previous post, but the real way to see the racquet is to be here.
Before it is too late!

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!

 

Head Squared

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.

Trying a new racquet?

Trying a new racquet is important! Trying a racquet that is set up for you is really important.

The following YouTube video explains our position on this important part of your tennis enjoyment.

Please let us know how you feel about trying a new racquet!

What About Me?

A lifetime dedicated to racquet technology and innovation

For more than five decades, I have been immersed in the world of tennis racquet and string design, manufacturing, and performance optimization. As the owner of Racquet Quest, LLC, I’ve combined deep technical expertise with hands-on innovation to set new benchmarks in racquet customization, diagnostics, and stringing.

My journey has been defined by a relentless pursuit of precision and performance—whether with professionals, college,  junior tournament players, in the lab, or in front of an audience, sharing knowledge with peers.

Advanced diagnostic technology

At Racquet Quest, technology and science drive results. I’ve integrated some of the most advanced diagnostic equipment available, alongside proprietary systems I’ve developed, to provide unmatched insights into racquet and string performance:

  • True Tension Stringing Machines – pioneering distortion-free stringing
  • Babolat Racket Station & Wilson Baiardo Stringing Machines – industry-leading accuracy
  • Babolat RDC (Racquet Diagnostic Center) – comprehensive racquet analysis
  • Questron proprietary string testing equipment – measuring ultimate tensile strength, stress/strain, knot strength, and more
    • Three-string comparative graphing tools – side-by-side performance visualization
    • Flex, In-Plane, and String Bed Stiffness devices – quantifying structural dynamics
    • Custom portable SBS device – portable precision testing

By combining these tools, I’ve been able to capture and refine the delicate balance between tension, elasticity, and structural integrity, pushing racquet performance beyond traditional standards.

Innovation in design and customization

Innovation has always been central to my work. Some of the highlights include:

  • Development of the Perfect Pallet grip system with a custom three-piece anti-vibration design
  • Expertise in Special MakeUp (SMU/Pro Stock) racquets for elite players
  • Custom racquet extensions and modifications tailored to individual needs
  • Proprietary software solutions for collecting and analyzing racquet and string performance data

These advancements have helped players—from juniors to professionals—experience greater consistency, comfort, and control on court.

Experience on the global stage

  • My expertise extends well beyond the workshop:
    • 50 years in racquet and string design and manufacturing
    • Professional event stringing services for several years at major tournaments
    • Seminar presenter for 12+ years, sharing expertise with players, coaches, and technicians
    • Delivered the acclaimed session “Understanding String” at the 1994 Super Show in Atlanta, hosted by the United States Racquet Stringers Association

This combination of hands-on service and educational leadership has helped shape best practices across the racquet service community.

Media and knowledge sharing

I believe that expertise should be shared widely. To that end, I’ve created multiple platforms to bring racquet knowledge to players and enthusiasts worldwide:

  • RacquetQuest.tennis – a hub for insights and resources on racquet technology
  • Racquet Quest Podcast, Podcastini, and Podcast Midi – covering everything from string science to on-court trends

Through these channels, I aim to make the science of racquets accessible to every level of the game.

Tennis continues to evolve, and so does racquet technology. At Racquet Quest, I remain committed to research, testing, and innovation that give players an edge while deepening their understanding of how equipment shapes performance.

Whether stringing for professionals, customizing for serious competitors, or educating the next generation of racquet technicians, the mission remains the same: deliver precision, performance, and passion through technology.
