Ok I tested the Haifu Whale and Shark with 2 layers of booster each and I am ready to report.
Honestly, without exaggerating, Haifu Whale is just a really really good solid rubber. Not much to complain about it at all. It's got a bit of speed, it grippy and spinny, its got good control, and it is just a looping machine. I felt like I couldn't miss any of my loops from any position on the court. It's similar enough to H3, but I would say it feels more like H8. It's a little faster and speed oriented than H3 is, thus more similar to H8. I got it for $8, so its the best rubber at that price that I have seen. It's better than Rxton 5 in my opinion. My only complaint is that I wish it was harder, but I only see it available on 39d on Aliexpress. So for $8, you get a rubber that performs similarly to Hurricane. I count this as a big win.
Haifu Shark is a big disappointment. I shouldn't be too surprised, as most Chinese companies can't make a very good BH tensor type rubber just yet. Basically, the rubber just doesn't have enough catapult and rebound, even with 2 layers of seamoon. Much of the time when I used my bh, the ball would slip into the net due to the lack of rebound. Even if it cleared the net, it often would land very short on the table. So this rubber to me just doesn't make sense on the bh. It kinda suffers from the same problem H8-80 does on the bh. My guess is that this rubber is very similar to H9. Next time I will try applying some VOC Haifu Whale 2 speed glue onto the rubber to see if that can save the rubber at all, but I doubt it.
