There is not any pictures showing the layers in his blade. Forums and social medias are only guessing that it in fact is a N301. Could also be a custom N656.
In addition to Chen Chen, Chen Meng is also using blue sponge H3. You need more strength to use Blue sponge rubbers due to its hardness.
Xu Xin is still using Skyline 2, he changed his blade to get more speed due to the new ball.
here is a picture of his rubber.

Fang Bo was using Viscaria at the latest round CTTSL as well. He was also using the Viscaria blade before he became a Ma Long fan boy. ;)
Nothing weird there.
That is what I heard, but major bommer that he withdraw from the event. Perhaps he saw that Anton Kallberg was participating as well and realized that he couldn't win the tournament. ;)
Just to get the terminology straight so what you call FB2 or FB carbon must be the commercial version of Fang Bo's blade which is the Bo 2.
I would believe FZD is using a W968 with Fang Bo handle, but I can't confirm it with pictures just yet.
