Head Radical MP 2023
You have seen the pretty pictures; now see the specs of this new Radical series!
We are starting our property review with the Head Radical MP 2023. The MP version will probably be the most popular due to the very lovely weight and “player” style head size of 98 inches!

Head Radical MP 2023
As you look at the following specifications you may notice the addition of some “numbers”, specifically “beam width”.
We have been taking this number for many years but now believe it is time to expose it to you, the readers.
Briefly, the beam height-to-width ratio contributes to in-plane stiffness which is important for consistent string bed stiffness (SBS).

Head…just when you thought it couldn’t get any better
The Head Radical has always been one of the best performance racquets available and doesn’t require much in the way of annual changes!
We think this new group is right on target! Adding Auxetic in the throat brings this series into the overall success of the Auxetic component!
We will be doing full reviews very soon, but in the meantime, take a look at these new Radicals!
The Team is the new “S” in the Radical Series! Based on our initial testing, we think this model has a trick up its sleeve!
The Same but Different!
How can two totally different things be the same in so many ways?
Here is a good example:
Wilson Sensation 16, natural v Wilson Sensation Plus 17, black.

Same but Different!
Looking a the stress/strain portion of the graph, it is nearly impossible to see any difference!
Both strings exhibit good elongation and elasticity.
Finally, when it comes to UTS the Sensation is a little stronger, as you would expect, for a 1.33mm string.
The Sensation Plus measures 1.26mm! So, the UTS is pretty good!
If you have been using Sensation but would like a black, thin string from Wilson simply use Sensation Plus!
Don’t be Beanie-less!

RQ Beanies!
Bag your beanie at Racquet Quest World Headquarters while supplies last. These are awesome!
Don’t be without a beanie for your chilly early morning tennis that is coming soon! Yes, even in Florida!
If you can’t stop by the World Headquarters we can send it. Just tell us where!

Bag a Beanie!
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 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.
