Comparing Racquets (for real)

The Racquet Quest podcast recently aired a session on comparing racquets, so, to be fair I wanted to post that same data here. If you listened to the podcast this will sound familiar.

These racquets are not random. These racquets are owned by a client that is seeking an upgrade without going overboard!

Here is the data.  Take a look then read what the client has to say about them.

Here is what Jess has to say:

“Hey, John –
Jess definitely likes the VS more than the Rafa. She said that she gets more easy power and stability with the Rafa but she’s able to accelerate faster on the forehand side with the VS.

She also felt like the VS was more maneuverable at the net. She said that if she’s in control of the point that she can really whip her forehand for a winner. She definitely noticed the lighter swing weight and liked that.

However, she also said that sometimes it feels a little unstable – like the VS is getting pushed around a bit. For example, she noticed that the head of the racquet can twist sometimes if her opponent nails a hard ball at her.

She has more control for sure with the VS – felt like she blasted more balls out with the Rafa. Overall, she likes the racquet- just would like a little more stability.”

By the way, Jess had not seen the racquet data prior to her hitting.  So, there you have it.  I believe you can see how much numbers help us find the right performance characteristics for a racquet.

 

Our Questron in Action!

As you know, Racquet Quest is a data-driven business, and data requires numbers. To generate those numbers, we have designed and built several devices.

One device is the Questron!

The Questron is used to test every string we receive, and the data is compiled to understand where that particular string fits.

So, instead of talking about it we have included a short video!

Thank you for watching our Questron in Action!  If you have a question, or a particular string of interest, please let us know.  We may have already taken the data!  On GASP.network there are many graphs of previous tests.  GASP.network is a membership ($40.00 one time) site.

 

 

The Elephant in the Room!

I suspect we all have heard that expression!

It means there is something that everyone tries to ignore, but it is too large to do so!

I recently read an article in Racquet Sports Industries authored by Georgetta L. Morque. The title is “Tackling Tennis Elbow.” Tennis elbow is an important topic and deserves much attention. Georgetta is writing about ways to mitigate tennis elbow after the fact.

So, here is the elephant in the room; STIFF string!

 

Let’s try to prevent tennis elbow, so it does not need to be treated!

When we say stiff, it means a string with less than 4% elongation at 60 pounds which is our testing parameter. Most strings, and for this discussion, strings exhibiting that property will be monofilament PET-based (polyester).

Fully understanding this required a lot of testing, both lab and play, for many playing styles and racquets. To make a long story short, as a racquet technologies business, we decided not to promote polyester strings for most players. That sounds silly, but why take a chance when you don’t have to!

Our success is based on helping you, the player, perform the best you can, so it does not make sense to promote something contrary to that philosophy. Probably 75% of our clients have come to us for something different, so we have a “head start.” 

So why do so many players use it or want to use it? 

We believe it is because they have not been exposed to alternative string materials. Some outstanding players at the pro level use it, so it must be good, and it is for about 10-11 games. Of coursemanufacturers and marketers of polyester string stand to make a nice profit! It is in their best interest to promote products by adding some terminology and material to make the string less stiff.

A polyester string is deficient in power and needs to be walloped, and the harder it is hit, the stiffer it becomes, which is the problem. Developing bodies can’t tolerate that level of impact for long.

Please let us know your experience with strings of any type!

 

Head Boom Team L 2022

Like the Head Boom Team 2022, the Head Team L 2022 has been much anticipated!

Finally, a 107 square inch head without the ridiculous thick beam and ultra-lightweight, a legitimate “tweener”!

The Boom Team L has the highest power level assigned to recent Head racquets coming in at “900”, compared to the Boom Team at 800 and the Boom Pro at 400. If a power racquet is what you are looking for, this may be a good choice!

The Boom Team L is a slightly longer racquet at 27.35 inches. This increase in length increases the swing weight without adding weight. You can think of swing weight as “leverage.”

The Boom Team L incorporates all the newest materials and design chops of the viral Boom Pro and Boom MP.

The specifications will give you a better idea of where this racquet may fit your game.

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.

Tecnifibre TF40 305 16×19

Tecnifibre makes some of the very best multi-filament strings using PU as a binder and performance component and the string packages all say “PU Inside” so I guess that is where “Foam Inside” comes from!
