Very fast rubber, that just got a sibling: https://www.nittaku.com/products/rubbers/post-59

Very hard to loop backspin. It seems to have very little dwell. The throw angle is not as low as advertised when trying to loop. I have to close the angle quite a bit. The balls shoot long. I have to tighten my strokes and technique quite a bit with this rubber. I wouldn't recommend this rubber.

I use it on my forehand 1,8 mm with my Latika 7 all wood blade (off -). As Nittaku advised, it works well with flexible and controlled blades. The best part is, you can smash to all spins and it is on the table suprisingly. It is really fast when you hit hard. I can make controlled spins and opening loops easily. Good serving and blocking too. Your opponent get some confused because of its low throw angle and short pips behaving. Short pips behaving is like ball drops early and smashing is easy. Amazing rubber if you master it with right blade.
