I'm using a Joola Aruna Off blade and have this rubber on both sides. The rubber I had before was Hexer Duro and I feel that this is both faster but has better touch?? My touch and control game have dramatically improved. I think that these rubbers are a lot more forgiving of variation and spin. While I feel like I get enough spin, I think I got more out of my Hexer Duro's. I think these rubbers keep the ball on the table more and I can add more variation to my spin because of the forgiving nature. I tried the 47 and I felt that they were even faster and I wanted more spin. I am very pleased with this rubber and will most definitely be using it for a while. Also, a point I should make, I play in a German league that still uses Celluloid balls. This could be a large reason why it's not as effective. These rubbers are designed with the plastic ball in mind.
