Andro has lots of decent rubbers. The best player in my club is playing Andro Hexer Duro rubbers on Both sides, not something people would recommend on this forum. (Soft and „beginner“ rubber)
You could go for the Hexer Power Grip (also available as SFX version, e.g. softer sponge), maybe have a look at the Rasanter line and choose something Like the R45 or R47.
The usual recommendation in this forum would be Yasaka‘s Rakza 7.
As a side note, I have had a look at the rubbers from our top 6 guys (all playing Saxony league with 1800-2000 German TTR) and 5 of them play slow and controlled rubbers. Only one is using a carbon blade. The spin they are able to produce is crazy. It’s (almost) never the equipment, it’s the player and his/her technique.
Final tip I can give to you: if there is a TT
Shop nearby, get some Consulting Over there. You Need to feel the blade and rubbers on your own and if possible you have to try it, people here can help you only so far
