I paired this rubber with the Friendship Battle II; however, I have only used the Super FX on my backhand. It offers amazing control and consistency, but it has taken quite some time to break it in. I have been playing with it recreationally for two months or so now, and it seems to just be breaking in. That is to say that sponge is finally starting to soften up, and the rubber is playing like it feels it should. While I usually don't use this rubber for my FH, it is obvious that, due to its characteristics, this rubber would be an exceptional one to loop with a very controlled arch and trajectory. Now that I'm really beginning to get used to the rubber since it has loosened up, I prefer it over my Battle II, and it makes me a very strong BH player.

Blue Sponge is meant to be tuned. I think this rubber, tuned; is better than any H3 neo except H3 national version (blue sponge). Once tuned, the rubber plays pretty well, good feeling (softer feeling), pretty good speed with good control and amazing spin. I use 5-6 layers of X-treme booster, the result is great. If you use it and don't use booster on it, you didn't understood the purpose of this rubber.

Pretty much the same rubber as ordinary Super FX on orange sponge. So read the reviews. Blue sponge is a bit harder and made for forehand. I use it on backhand, it suits me better.

The blue sponge version is made for forehand and it is (at least mine) considerably harder than orange 729fx. I have been playing for about 2 weeks now with this rubber (2.0mm) untunned on a stiga allround classic carbon and a yasaka extra 3d (both cpen) and tried it both on forehand and backhand. The rubber is indeed tacky and spinny but only if you are able to deliver fast brushing strokes. While ok for forehand, there are several better options even for players trying to learn the basic strokes. I would not recommend it for backhand since I found myself using too much wrist on my RPB to be able to apply speed and spin.

Very spinny rubber, with great control. It's not fast, but it's excellent for blocking and produces good services.
