Not a monster rubber in terms of speed, but pretty fast. Spin is above average, still not good enough for serves. Control gets this rubber the most points. Not very heavy, but not light either. Weights somewhat lighter than Barracuda. Loops are good, not great. Medium throw. Good for blocking. Less sensitive to incoming spin, compared to the rubbers with humongous spin (T05, Barracuda). Overall, a pretty decent rubber for backhand. Players who use backhand for blocking, counter and flat hitting will benefit the most from this rubber.
The best rubber i ever use, till today. that i used for first time the blue p2.
The speed of the s1 is fantastic , very good angle. But not good control. Youbhave to play somw time to get ok. But when you have played for a time the s1 is fantastic.
I used this rubber for a year on my forehand in MAX thickness on a Timo Boll Forte. It is fast, faster than S2, but not as fast as S1 Turbo. It seemed to me it is not as spinny as S2 and S1T. It is slightly lighter than the S1T. The durability of this rubber is pretty impressive. A very good rubber for a close to the table - mid distance looper
