The Rhyzer 48 has high throw and the 43 has medium high throw. Both are very spinny but the 48 has more potential spin than 43. In terms of blocking, the 43 is so much better because of a medium soft rubber.
I tried the Z1 Bluestorm yesterday and it was also really impressive. In fact, z1 Bluestorm is unlike any Donic rubbers I have used. The P-series were really not good and the Bluefire series were at least better than the P-series. The Bluestorm series well, this is the generation of rubbers along with Omega VII and Rhyzers that can completely outmatch MX-P. The only thing I needed to do is test the Aurus from Tibhar.
The 3 rubbers used can be classified as the Rhyzer rubbers on one extreme with the Omega VII on the other exteme side and the Z1 bluestorm as the middle rubber. Here is why:
1. the Z1 bluestorm has this power and spin better than MX-P but the Z1 seems to have better control than the Rhyzers because we tested the rubbers yesterday with the Z1 and the Rhyzers seem to be faster by a notch or 2 than the Z1. Even the softer Rhyzer 43 is still faster than the Z1 rubber. You could say that the Z1 seems to be a faster MX-P and also a bit spinnier. The topsheet feels grippier but the pip structure is shorter compared to the Rhyzer or Omega VII Pro. Still, the Z1 is very good.
2. The Omega VII is the easiest to use but in terms of speed, I still it still edges out Z1 in terms of speed but slower than Rhyzer 48 or 43. Spin seems to be more or less equal with the Z1 but it feels softer and you have to engage the sponge more in producing spin. With the Z1, thin brushes are easier to produce spin.
3. Rhyzer is still the the extremely powerful rubber here (both 43 and 48) but it needs a higher level of skills to fully use it.
