Donic Coppa X1 Gold

It is actually pretty nice rubber. I expected something faster but it's actually very close to Baracuda. It has a medium-low throw angle, speed oriented low arc and medium hardness sponge. The only problem I had with it was brushing and playing against choppers (it has a non tacky spin insensitive surface). For using it's full spin potential you need to push little bit harder and get the ball sink into the sponge. If you like this characterictic, it might be a good weapon for you. My overall rating is 8.5 which means a very good rubber but it's not perfect. It doesn't excel in any characteristic (you can find faster and more spiny rubbers on the market) but it's cheap and gets the job done well.

SUPERB for flat hitting and spinny serves.Works great on BTY Korbel wood.

excellent rubber, great speed and superb control.

nice rubber

I found it easy to control on medium stiff blade. Good smashes and loops, easy to block or push with, and long distance chops have a nice sting to them. Makes a great backhand rubber also. 1.8mm was 54 grams uncut
