Friendship/729 Super FX Blue Sponge

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.

better then normal version once you boost it, Is a lot more powerful and spinny. Slightly more catapult effect. Accually a decent pick for a vacation training bat.

Cheap and good rubber. It works shine with fast blades.
