I have used this rubber for my backhand for a number of weeks now. However, previously I used the original Airoc, for both my backhand and forehand. But there was a lack of power with the original Airoc which I didnt like for various rallies. So I made a change, I found Airoc Astro S was the perfect compliment for my forehand.
Its got speed and power along with good control. Its awesome for the touch game. My chops have more spin, serving has improved. Various rallies have been a treat with this rubber and looping and flipping have also been awesome. And one thing I did noticed, Astro S is much lighter than the original Airoc.
This rubber wasnt meant for a newbie, but if your advanced player who loves offense as well as being able to produce some good defense, this rubber is for you! Good luck.
