Yinhe 955 green/blue is easy to play, but does not cause a lot of problems for your opponent. Good rubber for first LP and learn how to handle then.
Next step up I'd suggest Dawei 388D-2.
More dangerous and more attacking capabilities, but faster and less forgiving for mistakes
I use red 0.7 and it's causing all kinds of trouble for people. It has gotten softer after 3 months usage (That's only 20 sessions for me) and the effect is big.
I've had so many comments that this is a nightmare to play against and results been good.
At first I found it stiff and couldn't sweep, but I can now.
Played a guy with a big FH who uses Grass on BH yesterday and he was shocked at what was coming back to him.
Also did a comparison on blocking against a looper. My spare bat has P3v which I always thought pretty nasty but the 955 gave him fits where he could loop 4 or 5 in a row against the P3v.
I am quite shocked how good this rubber is.
Just ordered a sheet of 8512 but not gonna change until this 955 is ruined. Any experience of 8512?
