I have used 1.8 mm red, very nice control for looping, chopping and nice for serves, of course. With this rubber all I wanted is to loop, lifting backspin is easy. Not so good for counterdriving, but all in all, very nice rubber.
Sponge is very soft! I like focus I and focus II more because with focus III you get the feeling that ball stops in rubber for bit of a second, so you get the feeling that this rubber is slower than it actually is. Which is the reason I don't like it. Otherwise, not a bad rubber.
hard sponge and soft topsheet, non-tacky, more euro than chinese type rubber. lower throw considering 729 rubbers. seems faster because of lower throw but this is not really fast rubber either. nice one, together with focus I, which one would suit better depends on style and taste of player, and on blade with which it will be matched
Nice rubber for FH. Soft sponge, higher throw, not fast - use 2.2 mm and pair it with OFF blade or faster, and enjoy. Good spin to speed ratio, not oversensitive to incoming spin, mostly mechanical, non-tacky spin, yet not completely euro but true hybrid euro-chinese rubber. For people liking this kind of rubber this one is really worth trying.
