Right here…Right now! Squared
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.

Launch Angle…what is it and how do we use it?
In the simplest terms, “launch angle” is the angle the ball leaves the tennis racquet relative to the court. That does seem simple enough, but how do we, or can we, contribute to it?
We are getting more and more calls asking what to do to reduce launch angle, as the game is changing to a flatter style, which generates a little more energy.
- Racquet Trajectory plays an important role in launch angle. That is why we hear “low to high” so often.
- A flat stroke can generate more ball speed but less spin.
- String Bed Stiffness is another property that contributes to launch angle.
- A stiffer string bed can reduce launch angle.
Many, many factors contribute to this, so we think this way:
As a player, you do not want to change too many things about your stroke; you want the racquet to do the changing for you!
OK, then! The first, and maybe the only thing you would do is pick up a racquet with an 18 x 19 string pattern! In most cases, you do not even need to change your reference tension(s).
We believe the 18 x 19 pattern is slightly more compatible than an 18 x 20, but either would work to help keep your launch angle under your control!
