R42 rated as medium hardness...I use R42 on fh because I also like soft rubbes,on bh softer and slower xiom vega europe.
As I read you, I think R42 2.0mm would suits you. Also R42 is not soft, its rated as medium hard on amdro website, so take black one, because black rubbers are softer, spinnier. Maybe you can check also andro hexer grip sfx which is medium soft rubber...
P. S. you pls check tt11 because you have big discount on 42 till end of this weekend (I ordered it).
