My own experience on blue sponge Hurricane 3 National rubber.
I put it on Xiom V1 Quad Cpen blade with ONLY ONE THIN LAYER OF DIANCHI SPEED GLUE. No booster or any other special treatments. My playing style is one-side Cpen loop/quick attack. I could do aggressive block and backhand attack against common side spin, back spin and top spin. It is not a good rubber for the people who are used to non-tacky rubber with/without cake sponge, but for tacky rubber fans, it might be good. How good is it? I am not sure, maybe better than the best, or only above the average.
Speed and Power:
My 39 degree blue sponge H3 is not extremely fast rubber, though I hit many fast balls with it. The reason is the blade itself. V1 quad blade is a really hard and fast weapon, which saves me work to make more speed. But BS H3 is definitely better than 40 degree common Neo H3 rubber in terms of speed and power. I used Neo H3 on my DHS 506, Xiom S7 Hinoki and Xiom V1 Qaud blades, 40 degree Neo H3 shows wild performance while BS H3 creates great power when I want. That is it, a rubber that trustily generates proper speed and power I need in training and match.
The top sheet of NEW VERSION blue sponge H3 national rubber is not as tacky as old version; it is same to common Neo H3 while some players complain that both common Neo and non-neo H3 are not as tacky as before. But yes, it is still tacky rubber, will never be defined as semi-tacky. BS H3 is so easy to make spinning loop, especially “modern top spin” loop that emphasizes forward power. DHS means to decrease the tackiness of its products in past time to keep up with today’s trend in table tennis game. I think DHS is successful at this point. BS H3 has higher limit on spin when I hit with power, not like Neo H3 or H3 provincial rubbers, and even better than other high end rubbers like Joola Rhyzm! It seems my opponents did not think the balls were very spinning when I neither thought the curve clearly showed “spinning signs”. Fine, I do not know why, but I like the results.
I love the feeling of BS H3 rather than any other rubbers I have used! I do not over glue non-neo H3 rubbers, so I am not sure about the glued feeling. But BS H3 improves my game very much due to its super good control or feeling in a great extent. Now I could push much better than before, especially some short back spin at my backhand; I am confident to finely adjust my paddle or wrist to persuade wider placement, and to make softer and hard block and backhand attack. The reason might be GEARS of BS H3, which is the key to ensure this rubber is easier to play. I believe BS H3 is very linear and has more gears than most of rubbers in market without booster! I have to say this rubber is really what I am looking for, it is tacky top sheet with classic non-cake sponge but very dynamic in Hurricane family without requirement of booster or gluing! It is not vibrating or feels hollow like many German rubbers, but seems like a Chinese rubber with sweet tastes of Japanese rubber, I mean BS H3 39 degree is not as stiff as classic Chinese rubbers.
It is natural that pro players do not need more power or speed from the rubber as table tennis fans do, since they are very good to make powerful shot with many common equipment, but they do need ones that ensure fine adjustment and clear response in high speed game. For myself, I do not think BS H3 rubbers will make my game much better, neither any rubber nor blade. To improve my game, I must do drills and train for longer time.
What BS H3 does is to ensure a large room for us to improve stably, when we cannot find any rubber or blade that will perfectly hit the ball automatically.
