Haifu Whale II National (Red Sponge)

I'm using the medium sponge version of this rubber (H37) in black on FH. It's also available in soft (H35) and hard (H39). This is my first Haifu rubber, I've been using DHS Neo rubbers before, mainly the Skyline 2 Neo. It's a fast rubber, definitely faster than the DHS rubbers. But it still has lots of very linear gears, meaning it's also easy to control in the short game and when blocking. Fairly lightweight, more so than the DHS rubbers. The sponge is slightly bouncier than the Neo sponge, even though it's comparable in hardness. Thus it plays a little better away from the table when looping than the DHS rubbers. The only real negative is that it just doesn't quite have the spin and "bite" on serves and close to the table loops that I got from the DHS rubbers. It's not a huge difference, but it's there. It's probably an effect of it not being as tacky as the DHS-topsheets. Overall it's a very good rubber indeed. It might not suit everyone though as it does feel a little like a compromise in styles between a Euro/Jap and a Chinese rubber. It seems to work well for my game though. The stand-out features are to me the linearity in gears and the feeling of control you get despite the speed of the rubber. Edit: I'm now using the hard (H39) version. Obviously similar to the medium version, but even faster on full swings while less bouncy in the short game. I really liked the medium version, but the hard version feels and works even better for me.
