XIOM Omega VII series
The Omega VII series by Korean brand XIOM are top-of-the-line offensive rubbers made in Germany, used by high level players and professionals alike.
They come in 4 different sponge hardness (the harder, the faster and the most spin capability, but also the more technically and physically demanding with less control): Euro is 42.5 degrees and good for intermediate players or high level players who prefer a softer sponge on their backhand, Pro is 47.5 degrees and fit for high intermediate players and above, Asia 52.5 and Tour 55 degrees are best for advanced players.
