Tecnifibre Fire 300

Tecnifibre Fire 300

The Tecnifibre Fire 300 is another great surprise from Tecnifibre.

Why a surprise?  This racquet shows up as a very stiff racquet both “out of plane and in plane”, as you will see in the following numbers.

However, the string pattern and spacing present a “canvas” on which you can create the string bed stiffness of your dreams!

Given the stiffness properties of this racquet, we wanted to test the “limits,” so we used a reference tension of 54, one less than the suggested 55 maximum.  Without going through all of the numbers, I can tell you that the Effective Stiffness is 26.7, which is well below our observed pain threshold of 30.0.

All of our demo racquets are strung with MonoGut ZX Pro (PEEK).  What you do in terms of string may change that number, but you can be sure the racquet stiffness can be mitigated by your choice of string, tension, and racquet technician.

What is “Soft”?

Jul 3

Posted by

For many years, we have been testing string for elongation and subsequent power potential.

There is a new batch of strings that include the term “soft” in the promotional language, seemingly in an effort to mitigate the injuries associated with very stiff strings.

At some point, we can go into detail about how the soft version of a string compares to the non-soft version; however, for now, I want to reintroduce you to a post we did in 2016… almost ten (10) years ago!

Thank you for reading this again.  It is important “Play Harder not Hurter™”

Right here…Right now! Squared

Apr 3

Posted by

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!

More Linearity

Mar 31

Posted by

Every string we use and even string we do not use goes through our Questron testing cycle.  We have discussed this before, and a video on this site shows the Questron in action.  We have updated the Questron significantly since the video was made…and it isn’t quiet.

We want to discuss “linearity” and how it can help when choosing a string setup.

We used these strings recently, and they were not chosen for any reason other than availability.

The first graph shows highly linear strings. The straighter the line from “0” to “fail,” the more linear and consistent the string is throughout its life.

 

 

 

 

So, what does linearity do for me?

  • Maintains tension
    • Minimizes energy loss
  • Maintains playability
  • Maintains consistency
    • Maximizes control
  • Maintains predictability
    • Provides confidence throughout your match

This property is essential to us. That is why we offer an alternative to non-linear strings.

If you would like this information for your favorite string, please let us know, and we will try to provide it for you nd all other readers!
