I guess, two more things on this subject.
I have a friend who had been playing with Hurricane 3 right from when he started and he recently switched to Euro style rubber. I asked him why out of curiosity and he told me that he had developed some bad habits with the Hurricane because of how much the tackiness of the rubber does for you. I thought, that is interesting. I had been using Euro rubbers (Tenergy) on my forehand until last June. In June I switched to Skyline to try it out. It took me a long time to get used to certain things about using it. Particularly in attacking underspin there were bad habits I had as a result of using Euro rubbers that I feel switching to DHS tacky rubber corrected. So for someone who has been using Chinese tacky rubber for a long time, you probably get into different bad habits and lapses in technique than if you are using smooth, softer Euro rubber. Probably, in the end, developing good technique so that you can use either well would be ideal for improving your game. I know I do not have any trouble adjusting when someone gives me a racket with Euro style rubber on it.
When I put my new H3 NEO on the other day I did some tests with it. I was bouncing the ball on it in different ways and comparing the results to the Tenergy side. When I just dropped the ball on the rubber to let it bounce from about 8 inches above the rubber, there was almost no bounce. When I did this with the Tenergy there was a lot of bounce in comparison. When I threw the ball at the racket from an angle so that the ball would go straight up with spin, on the H3 side, if I threw the ball moderately, not too hard it spun well but did not bounce up too high. When I did this with the Tenergy side I got the same basic spin but a lot more bounce. When I threw the ball hard, H3 had more spin and just as much bounce as Tenergy!!!! I think this is why H3 NEO has so many gears.
Now I know that this sheet I was given came from where the Chinese team trains, so I don't know how it would compare to what they are selling. And I know people are saying that H3 NEO has a 39 degree hardness. The sponge on this sheet specifically says it is 37 degrees and it feels softer than any DHS rubber I have felt in the past. It actually feels a lot like Tenergy 05 in hardness but the topsheet is softer than the Tenergy topsheet. That is also different than anything I have felt from a DHS rubber.
