Mind you, what you see is not what you always think it is. I just cannot disclose anything more. There are 2 things here, I am wrong and the people from Xiom are wrong ir you think you are correct,
Riganis just like an older generation of ESN rubbers. It is more or less in the level of Aurus rubbers. Rigan is like Musa 3 so the spin for that is not greater than that of the Vega Intro.
I gave my DNA H to 2 competition players who practice everyday and the rubber has promising durability. The rubbers still has good amount of spin even after a month of continues playing
