Good rubber, more for someone who needs control above all, cause it is really a very forgivable rubber.
On fast blade can be dangerous too.
Youth players in teams in Germany play with Adidas R4/R6 combo, that should say a lot.

Thickness: 2.2mm or max
Weight: Uncut 53-54 grams 171x171mm; 38 grams cut to an Adidas C500 carbon blade
Sponge hardness: about 36 degrees in a DHS Scale
Basically, the faster rubber in the R- Series. It has the same topsheet with the R6 but with a harder sponge.
FH to FH, Bh to BH:
same with the R6 but faster by 10-15%. R6 has more control and dwell time.
A bit more stable in the pushing department because with the harder sponge, the ball doesn't pop up.
on fh and bh loops i liked this better since I could brush the ball better. Its really a matter f preference though since I have a somewhat Chinese stroke which emphasizes more on brushing the ball and not hitting through the sponge. The trajectory is still low a bit higher than the R6 but still considered low and long.
Countering, blocking ad Smashing:
Same with the R6 but faster and the ball has a lesser dwell time.
All in all the R6 and R4 have surpassed my expectations for their level of rubbers. These rubbers are the first generation of Adidas rubbers the company has produced. It can compete with the level of those JO Silvers and JO Gold but are faster and more controllable. I have noticed that the topsheets are much durable than that of the JO series too. These 2 rubbers are user friendly especially to beginners and intermediate rubber though I am not saying this are beginner rubbers only. These rubbers are good because they have more than enough speed coupled with very good control. The best thing about these rubbers is that both are very light and when i weighed the set up: R4 38 grams + R6 36 grams + C500 blade 85 grams = a staggering 159 grams only! That is very, very light compared to 170-180 gram blades that are already considered normal in weight
