Tecnifibre Black Code 1.24 and 1.28 review
We have a new winner in group B !
Tried 1.24 gauge in new Tecnifibre TF40 16x19 (but tight pattern) 315g and 1.28 in Angell TC95 16x19 (but open pattern)
I have to say, TF40 16x19 is my new top contender for
ultimate racquet of choice (click) 
BUT let's focus on the strings now!
Black code is a 5-sided string with high stiffness rating but quite efficient energy return %. From my experience it's like trying to mix two different personalities. One that is cold and very calculative and second one hot-tempered and bitey

The dominant factor for power level is overall the stiffness while energy return % is like a "limiter" to your input.
How to understand it?
Let's take out the stiffness factor out for a while and focus just on energy return %. Let's say your swing acceleration has a force "input" from 1-10. Energy return % will take that number , adjust accordingly and launch the ball with some added info. The higher the energy return % the more info you are adding, increasing the final output.
Stiffness kinda adjusts the amount of your input and passes it on to energy return % lol
In short:
If you had a "tennis plugins/effects chain" it would look like this:
Your clean power just before the ball touches the strings (input 1) -> stiffness rating (increasing or decreasing input) -> energy return % ( how much of this input do you want to let through or maybe even add more signal?) -> final output
So if you look at for example Luxilon Original - It is relatively stiff (213 stiffness rating) with 85 % energy return which is making it a very very control oriented string. The amount of energy return combined with stiffness are encouraging me to speed up my swing because low energy return is keeping me safe from pushing the ball out. - it's more difficult to hit a too short ball than too long.
Now back to Black Code (let's start from 1.28 gauge) - stiffness is quite high at 250 with energy return at 87%. All I can say is that the performance is very interesting.
I noticed that there is a perfect sweet spot of my initial input (how hard I try to swing) where the ball is very heavy, controlled with rather linear response. The stiffness provides control but energy return is giving me the performance and actually I would say Black Code is a very comfortable string with a nice dwell time and pocketing sensation.
I can FEEL it. If I can feel something then I can adjust to it from shot to shot and replicate on demand

And everytime I decrease my input (slow down my swing) or try to go for a crazy off the cuff winner then I am being punished for stepping out of that sweet zone (I loose control and the ball goes too short or too far).
To me - that's actually a very good quality because it teaches you to play "in the zone" and "learn" your swing. Look at Djokovic or Medvedev - they are not the attackers, they just contantly hit their targets and make it look easy. So relaxed but manages to play very deep over and over again. Black Code to me is for a playstyle like this.
Launch control is perfect. I was not surprised by anything. String listened to me and my intentions
It felt much more comfortable than Luxilon Original and Tourna Silver 7 Tour.
I can see why there are many brands trying to copy this formula (without pointing fingers)
I think Millman in the interview once said he prefers Black Code over Luxilon Alu Power because he is getting the same top performance BUT in a more comfortable package.
I usually prefer control oriented strings so no surprise that I am enjoying Black Code.
I would prefer Black Code to be a bit more "tempered" (not sure if that's a good world?) so I could go a little bit crazy from time to time or so it could let me slow down my swing (push the ball) when under much bigger pressure. On the other hand it pushes me to play good.
1.24 Black Code is like a thinner brother of 1.28 gauge lol. Everything pretty much the same just "more".
So a bit more power, a bit more spin potential. Which one is better? For me it's down to string-racquet combination. People were noticing quite a lot of spin from my TF40 with 1.24 Black Code.
Compared to Mayami Big Spin (which was so far the leader in group B) Black Code has much more linear response with a bit more connected feel and better volleys while Big Spin is an ultimate spin machine.
Similar strings from different brands:
Solinco Confidential (Black Code has better tension maintenance and longer playability duration with control, rest is very similar)
Head Lynx Tour (Black Code is more comfortable, Lynx Tour has less power, rest is similar)
Mayami Hepta Power (Black Code less power, Hepta Power more comfort, rest is similar)
Griekspoor is using it and managed to win 8 record-breaking challengers in one season with his endorsed TFight RS305 18x19
Compared to Tecnifibre Razor Code:
Razor Code offers even more feel,comfort and a bit more power with bigger "sweet spot" but a bit less spin.
I'm not sure which one I prefer Razor Code or Black Code - depends on the racquet.
RATING: 7.3
