Well, Nittaku does it again! I expected this rubber to create great spin and speed, but I was taken back a little bit on how well I could place my serves with this rubber. If there are any downers to this rubber it would be that I did expect a little more speed from it (still plenty fast), and that it actually does need some breaking-in time (it's possible that I just needed to adapt to it). I use this rubber on the the Nittaku Flame Carbon (beautiful combination) I have used many different company rubbers (Stiga, Donic, Andro, DHS, ect.) But the only company I keep coming back to is Nittaku.
