RITC 729-2 Sensor Sponge

I've also heard it called RITC 729-2 New

 

I just bought this rubber and have been playing it for a couple days. I like it a lot on my forehand... but i am unhappy with my backhand right now. I want something really close to this. I haven't tried too many rubbers before, so i need some helpful advice.

 

I want something with speed and spin characteristics that are pretty close.. maybe a little slower, but not too much, but something with a little bit softer sponge.

 

rubbers I've tried:

Sriver EL 2.1

Sriver FX 2.1

RITC 729 Focus III 2.2

RITC 729 Geospin Tacky 2.0

Tackifire Special Soft 2.1

and of course the one I'm enquiring about.

 

The only thing i could think of out of what I've used is the Focus III, but i think maybe it's too soft.. atleast its not spinny enough. So if anyone has suggestions I would really appreciate them.

 

BTW: I forgot to mention.. I'm looking for another chinese rubber preferably.. I can't afford to buy 40 dollar rubber sheets
