I changed my DHS Hurricane 3 blue sponge 42° on my fh for this rubber. My review will be comparing them. The first noticeble differnce is the catapult effect. While the H3 has none, the O7 china has a noticeble one. It is fairly quicker in short game and blocks than the H3. The second thing you notice is the lack of tackiness. The H3 is a ocean tackier than the O7 china. This impacts the game a lot, becaus with the H3 you can brush the ball as thinlly as you want, and the rubber will grip the ball. With the O7 china was happening at the begining the ball slipping on the rubber. After a few hours you get used to both of the things I said. In general, the H3 is spinnier (not saying the O7 china produces low spin, it's just not as much as a H3). Now lets go to the similarities... the throw angle is very similar, the speed on drives is very similar, and the hardness is similar as well. I would say the O7 china is easier to play with because you don't need to activate every single ball due to catapult effect (noticeble when compared with the hurricane, but not high at all compare with an euro rubber). Conclusion: the O7 china is a very good rubber, it is a fast rubber and gets faster with the force of the shot. It has medium control, and it is not the easiest rubber to use. It demands good technique and force. If tpu like to play passive shots this is not for you. If you thinking on a replacement for the Hurricane, I would say it is a heavily tuned hurricane with 85% of its tackines gone.
I´ve tried lots of diferent european ruber as a Reverse Penhold Backhand player, but when i first started to see that my forehads were lacking of spin i tried chinese rubbers, i proved all the commercial brand of dhs and definetly the tacky topsheet was a great decision on my game in general, but when i first tried this rubber, i fell in love inmediately, i played with it for about 1 year and i learned that it may cant be the fastest rubber on the wolrd, but if you need an allround rubber that works great to transition both ways from european to chinese national or boosted rubbers, this rubber is great, it keeps the feeling and consistency of a chinese rubber loop with lots of effect and the power of an explosive topspin punch or drive by a european without lacking control, the counter topspin game is one of the biggest advantages that the rubber has over chinese ones, as a control/attack player from middle table, i must say that this rubber works great even on wood blades, if you are a defensive player, the forehand chop is very good, i also have to say that a good technique is needed to play short game and serves, but in my case, the penhold grip helped a lot on this point, so in general, underated rubber, highly recommended, 9 out of 10
After Vega DEF seems to have been discontinued, this seemed to be a good replacement.
Slightly softer now at 55 degree, but still plenty of power.
Can do everything reasonably well, no real weaknesses apart from of course being pretty damn hard and imo requiring some mild boosting occasionally to reduce the physical demand, help with recovery, help against humidity and so on.
In short, this rubber is not exciting at all, but it does what you would expect from it and basically causes me to not think about the rubber and instead about technique and positioning, which is good of course.
Would recommend if you have enough technique and power, like to boost a bit and look for something stable, spinny and powerful. But there may be better alternatives among current gen that I have not tested (yet).
Spinnest that i have used and very controllable on blocks, pushes and chops. Still pretty fast but slower than Omega V Asia. My offence is probably +100 points using this rubber. I did have to change my strategy and technique to use it for full effect.
