Why do Butterfly now claim that Tenergy 05 is spinnier than 05fx?

[MOG]

ten years ago if you went on butterfly selling websites - the numbers they gave you for spin were higher with 05fx than 05.

05 had more speed than 05fx but less control

now if you go on the butterfly website 05 is significantly spinnier in the numbers than 05fx.

How can these 2 things be correct?

Have they made 05fx worse to encourage people not to use it?

In my experience 05fx is a very spinny rubber for a non tacky rubber

The focus (and ball reaction) with the new plastic ball is different.

Softer is easier to produce spin and more forgiving. Harder has a higher spin ceiling, which means the maximum spin you can produce with harder sponge is higher, but you need a much faster arm-speed than with the softer rubber to produce this ceiling.

According to Butterfly, they revised the numbers in 2023 due to improved measurement methods.

It is just marketing

If you have to swing hard to get the maximum spin, that means there are less chances for deception and variation surely.
Even if I have a powerful heavy spin/speed fh if its always the same shot better players adjust, then its just about who is the better player.
I still use 05fx, although with the modern balls its very rare that people block a heavy topspin long or high.
Whenever I try 05 it just don't seem as spinny. Maybe i just have bad technique!

Spinsight now exists for a more objective perspective on this. When you say spinny, do you mean absolute revs per second or do you mean the ration of revs per second to linear speed? And of course there is also the question if in what zone of speed and spin do you generally play in. I find that the more you try to reloop the ball early with power, the more you like harder sponge and the more you try to play flat early with power, the more you like softer sponge.
