I have the Rakza 9 and its not the same sponge as 7. Rakza 9 has clearly bigger pores then 7, havent played with it yet though. The premier is tonight :)
I have the soft version, both FH and BH, and its the best rubber I've used. Excellent spin, speed and controll. I'm going to try the regular version to though because soft is not optimal for smashing.
I would like to see two Shakehand and two penholders. Chen Qi, Zhang Jike, Wang Hao and Xu Xin. I don't think Chen Qi will make it but I hope so since he has the most awesome and fluid style :)
Timo Boll is only nr.1 because the chinese haven't been in enough ITTF tournaments to earn points. The amount of people playing and the intense training is why china is the best.
As soon as the Chinese players start to play tournaments that give points they will be No.1 again, Timo is not as good as Ma Long, Wang Hao, Zhang Jike imo
