Tecnifibre TF40 305/16M
Tecnifibre has introduced the new TF40 series in a very much appreciated 16 x 19 string pattern! The 18 x 20 pattern is a good one but we think it may intimidate some potential buyers.
This initial review is for the 305 series, with 305 being the gram weight of the unstrung racquet, in case you didn’t know!
As with all the Tecnifibre racquets we have been in contact with this new one looks to be very well done with some subtle details that are interesting.
One is the textured decal on the “Tecnifibre” side of the shaft. It is obvious to the touch and we think it adds to the overall aesthetic of the racquet. Another one is the slightly asymmetrical terminus of the shaft at the grip top. It is barely noticeable but I like it!
One of the additions to the series is the “Foam Inside” component. Some players really like the “feel” of foam-filled racquets and this one is filled to the brim! Since it is filled with foam Tecnifibre does not see the need for a “trap door” on the butt cap, so if any work needs to be done back there the butt cap needs to come off. I don’t think there will be much needed so the solid butt cap eliminates the potential for “buzzing” which has plagued some racquet models.
The TF40 305 is a thin beam, 22mm all the way from the grip top to the very tip of the racquet. with a box shaft and an elliptical head cross-section.

New Head Racquet Names
There is a need for clear descriptions of tennis racquets so you, and we can make good buying decisions.
Head has applied this to the Prestige 2021 Series and it is a little confusing, maybe. So here is the information as we know it right now and according to the racquets in stock is correct:
New Head Prestige Names
You can see the entire Prestige 2021 Line-Up including additional data here
…then there was this big BOOM!
Boom Pro
The big BOOM you heard was the arrival of the new Head Boom MP and Boom Pro racquets at the World Headquarters!
Head Boom MP
This is very exciting news for those that have been waiting!
The wait is over!
For those that pre-ordered, your racquet will be prepared for you quickly. For those that have not yet tried the new Boom series…what are you waiting for?
We also offer Full Custom Boom MP and Boom Pro racquets that are built for you including longer length if desired.
Either way, we think you will be hearing more big Booms very soon!
Head Lynx Touch! Two for One?
Several weeks ago we received the first sets of Head Lynx Touch 17 gauge strings. Yesterday we received the Lynx Touch 16 gauge version and want to share the differences…numerically!
Quickly, this string is composed of two (2) separate but “combined” filaments. So, is this a monofilament or a multifilament? The numbers indicate it reacts like a monofilament as we have become familiar with it.
Head Lynx Touch
Let’s start with the 17 gauge version:
Lynx Touch 17
The area under the heavy red lines is the “stress/strain” curve and we see that this string takes 23.5mm to reach the 50-pound mark. This is just a number unless it is compared to other strings so it is neither good nor bad, right now!
You can see that the string will hold up to 149.8 pounds before it breaks. This is tensile strength and may be important when considering the amount of “notching” that can occur. The “knot” strength of this version is 132.4 pounds.
Now let’s look at the 16 gauge version:
Lynx Touch 16
The difference is subtle. The 16 gauge version is a little stiffer (expected) and a little stronger in tension (also expected). The “knot” strength of this version is 133.6 pounds.
What is interesting is the “grouping” of the stress/strain cycles on both strings. They indicate a good elasticity. The closer to the “zero” point on unloading the better!
In our opinion, both versions of the string would be considered “stiff” and suitable for the player looking for a stiff but stable string as our creep test confirmed.
If you currently use stiff strings and would like better consistency this would definitely be a candidate ./
