I don't believe this rubber doesn't have treated pips. Spin sensivity is too low and the throw angle is too flat; Stefano doesn't even need to chop-block—the ball carries a ton of backspin on a simple block, and even a light push against backspin results in topspin.
The version from the store doesn't play like this. The rubbers have been cured somehow. I can say this with 100% certainty. I've been playing with these rubbers for years.
