Red was my FH side.
But actually i dont think its a perfect equation for oxidizing.
I had a few rubbers that i mustve bought in 2008. So after 14 years, they are not anywhere near the oxidation level of this sriver.
They sriver is hard as plastic and is completely not playable. The 14 year nittaku rubber is still like new. I played it and it is still bouncier and faster than chinese rubber like ak47. It not hard at all, and the sponge is still soft and elastic.
If the sriver is a 0 in performance, and a new Fastarc is 100, this 14 year nittaku would be like a 94. It really hasnt oxidized much.
