New string information
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!
House Cleaning!
Every once in a while Racquet Quest decides to do a little house cleaning and that means opening boxes that have not been open for a long time!
And surprise! We find a lot of really interesting and exciting tennis racquets! Most of these have been on the Racquet Museum site but now it is time for them to find a new place to hang out!
Most of these racquets are new! Many have been strung for evaluation purposes but have not been played with! All of the racquets will be fitted with a new grip. All the racquets will come with the string that is now in the racquet, unless new stringing is requested. All racquets are sold “as is”. Most of them are new, but the string may be several years old. There will not be any “junk” offered, just good racquets!

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!
Head Graphene 360+ Speed Lite
As you probably guessed, this is the lightest of the Speed Series, 100 square inch head size, at a weight of 281 grams (9.91 ounces)!
There are several positive features in this racquet and one is the reasonable flex (stiffness) of 63 RDC, plus the uniform string pattern that provides a consistent hitting experience needed by developing players. This pattern should contribute to extended string life as well.
Head Graphene 360+ Speed Lite
As with all light racquets, this one can be customized as the need or desire arises, and I think that will happen more quickly than most other racquets.
This is just too light, in my opinion, for players wanting to improve all aspects of their game. Remember, weight is your friend! However, if you prefer a light racquet for any reason this is a top choice!
As I am working on this post I realize how much trouble it is to switch between racquet reviews for comparison so here is a link to the Head Graphene 360+ Speed Series Comparison.
