The R47 gives a balance for speed and spin. This is a very fast rubber but also it is very spinny. This has a medium hard sponge at 47 degrees. When looping it has a medium arc. This rubber is for advanced players only as this is very fast and takes a bit of skill to control. This is ideally paired with carbon-arylate blades or just all wood blades to maximize control. This feels like a Joola Rhyzm 48 but a touch softer and spinnier.
