This carbon-hunt is a bit funny. If you buy a fast Butterfly carbon blade and put on some Dignics 05 or Tenergy 05 MAX, and have played for say less than 5 years. Of course you have a huge problem. But there are wooden blades that are as fast as all these carbon blades as well. So if you slap the Butterfly rubbers on these wooden blades, you will still have a lot of trouble.
The biggest problem is that non experienced players, use setups made for more advanced players, and they get "bounced" away. Many players/parents want to take shortcuts to get ahead, but the only thing they do is prohibiting themselves/their kids to learn proper technique and prepare them to be able to handle these setups in the future.
I have a friend whose children play table tennis since a year back. The kids are 7 and 9 years old, and he asked a coach what rubber he should buy for them. Tenergy 05 MAX was the answer. Because the coach himself plays Tenergy 05.
And the youngest already had a fast Yasaka Offensive blade to put these rubbers on. These kids must have the opportunity to practice their technique for some years before even thinking about these kinds of rubbers and blades.
Now the youngest plays with Sanwei Fextra Allround and Sanwei Ultra Spin on both sides instead and feels that he for the first time has control over the game, have to work to get the ball over the net and is practicing his technique.
Now we perhaps moved away from the topic, but I think this is important and it could have something to do with all these carbon thoughts I guess.
