I've been playing with the Donic Z1 Turbo, which I love. Then I tried this rubber, and I find I like it better. It's a personal preference about the feel of how the rubber hits the ball.
The Z1 Turbo is a very good rubber, and I still play with it once in a while. I would rate both rubbers just about equal.
With the Omega VII Tour, I do find that the edges do fray easier than the Z1 Turbo, if you are a careless player like me; I tend to brush the rubber on the table occasionally while I play, and the Tour would show the worse for wear more than the Z1 Turbo.
I am an all out attacker, and I'm so happy to be able to play with both the Z1 Turbo and the Omega VII Tour, even though the Tour is my favorite at the moment.
