I bought a new Zyre 03 recently and I find it fast and spinny, with enough control, but it does require experience as it isn't a rubber aimed for beginners, it does require a good understanding. The spin is rather impressive (imo not as good as Hurricane and other Chinese rubbers but for what it is, it's very impressive.) You also need a confident shot, you can't just do a "nothing" shot and expect it to be decent like Tenergy. For this rubber you need to hit it confidently to get the best out of the rubber. For me, the rubber suits my backhand very well, I might switch to it fully. Compared to D09C I would say it's a little less forgiving and faster. The spin is pretty similar though. The thickness I haven't gotten used to yet and I find the thickness really weird but I like that feeling. I would recommend this rubber to those who want good enough control without it being crazy fast and bouncy like the Dignics 80 or Tenergy series, while having an impressive amount of spin and have good power.
