I have been using Viper Soft OX on my Butterfly Gregaly blade, I have Blue fire M3 on my forehand, for the last 6 months and find that the service receive is much more easier with this rubber as compared to any other of its class. Prior to this i was using D Tech Grass but Viper Soft has more reversal effect. Further close to the Table block in particular Chop Block is almost deadly. One can have good chop away from the Table as well. The only problem is the longevity of the rubber.

Like most pimple players we all like to experiment with different pimples from time to time. Used this rubber a couple years back in a 0.5mm jacket. I loved it, it did lovely strange things to the ball that left my opponents very uncomfortable, control was excellent, any tricky serves that kissed the viper was returned with poison. Hits with this rubber if executed right didn't come back.
The soft pimples easily flexed over to give that unpredictable return causing opponents to put balls into the net or to hit long, sometimes they missed the ball completely.
The only down side is because this is one of the most softest rubbers (if not "the most") on the market, the rubber tends to rough up at points of contact with the fingers or thumb.
Because of this I tried other rubbers but after 18months have decided to go back to the viper soft.
