So funny how you all think Fan Zhendong is using Viscarie with Infinity handles. I think it's much more likely that Stiga is just preparing some customized Infinity handles for him. Stiga has together with Butterfly the best blades in the world, I don't think it would be a problem for them to produce blade which would suit Fan Zhendong's need.
OT, why are you complaining about the price? Much cheaper then all the expensive BTY blades. It's also a blade, you don't have to change blade every year. MUCH cheaper then for example a Tenergy which you have to change every couple of month.
A blade is like a jacket, you can keep it for a couple of years and the monthly cost at the end is quite low.
For sure getting the Xu Xin Edition, don't been this excited for a blade in a long while!
Stiga are sending him and Xu Xin blades, so your theory that they are giving Fan Zhendong customized handles is incorrect
