Trying to replace a rubber, it's really old and I just boosted it and glued it on mine for some testing. It actually plays nice I was just curious what hardness it might be 45? 47? doubt its 50 deg. Will probably end up looking for modern alternative that is in production unlike this. Would be great if somebody can tell me exactly.

From OOAK sponge hardness table, Gold is 45, Platin is 48 and Platin Soft and Silver is 43. I just bought 2 so I think Donic is still making it. It matches well with their Waldner WC89.

Hello, i have played with this Coppa JO Gold on my Waldner Senso Carbon blade, and i really liked this rubber ! Lots of speed and spin, only for attack style play. I found it difficult to keep the ball short on service returns and short play in general.
When you accelerate, there is some serious speed and spin ...

Hardness i would also say 45 degrees (as to compare : a Sriver-L would be like 40 degrees hardness to me).

I would suggest the Tibhar MX-P as a replacement for this rubber, kind of similar play, but a tad more feeling maybe for the MX-P.
