I always use hard sticky rubbers on my BH . I like to spin and brush. I also feel that soft rubbers do not give me the same control. Boosting does give speed but I seem to be able to generate enough. I am just a mediocre club player not like Tomo Harimoto san 😄
No there is no special factory treatment. Normally , when there is special factory treatment the rubbers come in a Vacuum pack but theses rubbers come in standard packing. I never used a black of the R9. For my forehand (black) I use the Rxton 3 pro
I prefer STAG- Seemless, most notably distributed as the Stag Peter Karlsson 40+ 3-Star or the Stag 3 Star Supreme—is a highly regarded plastic ball known for its uniform bounce, durability, and roundness compared to traditional seamed alternatives
Also just kidding BUT actually yes they are. Japan features an enormous shortage of kids, people live long and there will be not enough income generated to look after the oldies. Women are educates as well as men and refuse to get married have kids and play: Traditional housewife roles...
I am normally paying about NZ$ 15,- for the rxton 3pro which includes postage to New Zealand and 15% Tax. Nobody will consider faking a dirt cheap rubber like this. Now Fake Butterfly rubbers are a completely different animal. 😆 😆 😆 😆
