Jack is Headed to France!
Many of our readers know Jack Anthrop, but I will tell you a little about him just in case you don’t.
Jack Anthrop
We started working for Jack about six (6) years ago, at which time he switched to Ashaway MonoGut ZX. Since that time, Jack has progressed at a stunning rate, now with a UTR of 13.26!
Jack is using the Head PT113B Speed custom racquet and now a new fiber made by Victrex, a UK company that specializes in PEEK materials for high-performance applications which is the Ashaway MonoGut ZX and ZX Pro material.
But, the big news is Jack is headed to Paris, the one in France, to play in the French Open Juniors! Jack and his partner, Max McKennon from California, are in the main draw doubles!
Jack has a great chance to be in the main draw singles as well.
Max McKennon
Congratulations to Jack and Max on this great accomplishment!

We believe this is an exciting step forward in specialized tennis racquets and preparation.
We are anxious to hear your thoughts on this move to better racquets for everyone…especially you!
Head Graphene 360+ Gravity MP/Tecnifibre RPX
Normally our racquet reviews are when a racquet is brand new; however, this is a case where the updated string, RPX, from Tecnifibre is an excellent opportunity to add another review to the site!
There are some excellent reasons to review the same racquet again with different string or tension settings.
- It allows us to evaluate new strings for comparison purposes.
- It will enable the player to demo the same Racquet with a different string.
- The string can affect the overall weight to a small degree but significantly impact swing weight.
For example, this racquet with Victrex 7718 PEEK string (15.9grams installed) has a swing weight of 318. With the new Tecnifibre RPX (18.0 grams installed), the swing weight is 325. That is not huge, but it is different.
Lead tape, commonly used to increase swing weight, weighs in at 2.8 grams for 12 inches! So, slightly over 2 grams of additional string weight in the strung area contribute to the difference between these strings.
Of course, this also means that swing weight can be reduced, somewhat, by using lighter string! We weigh all of the string we test for Power Potential, so we know which string can benefit either swing weight preference.

Tecnifibre Makes a Move!
Does Tecnifibre have the “answer”…again?
We all know Tecnifibre for its terrific multi-filament strings that set the bar for strings of the material and construction. Several years ago Tecnifibre introduced a string that was intended to be arm friendly to counter the increased use of very stiff string.
Since that time Tecnifibre has gotten into the polyester string arena in a big way but they have not forgotten the player that needs a more comfortable string.
Not long ago Tecnifibre introduced Duramix 16 and 17 gauge string. As the name implies there were a couple of fibers used to create a stiffer but still comfortable string. We have used, very successfully, the Duramix 16 and 17. This is a great option for juniors that need some durability without sacrificing their arms.
Now Tecnifibre has introduced Triax! Is Triax the new “answer?”
Triax will replace the Duramix name but deliver the same or better performance and comfort.
Take a look at the String Characteristic Data to see how these new Tecnifibre strings stack up!
