Take a photo of the logo of the rubber (I need the details of the Chinese logo). I can have a look at it even if you don't have the photo of the back of the rubber.
I have been using this blade for nearly 7 months and I have tried a number of rubbers on it. I think this is a good blade but may no be faster than Viscria than you thought.
Obviously, China will take the golden medals in both team events, if everything goes well. But who will take the silver and bronze of man and woman team? :)
