Hello, I know that Ma Lin played with Bryce Speed FX for his backhand but he changed rubber for World championships in Paris in 2013. I got photos and i see that he has a butterfly tenergy but I can't see if it's a tenergy 05, 05 FX, 64, or 64 FX. Can you help me ? I would like reliable informations. (on the first photo, you can see the butterfly logo) Thank you !!!
