Android Question

Tablet Name: Xpod arc x
Android version:4.2.2
recovery: android system recovery 3e
processor: allwinner a31s

The tablet came prerooted, I updated the su binaries.
as of now its unsupported on cwm recovery.
Do you suggest any other cwm recovery that i should use with this tab, which would be compatible and wont brick my tab....
Or plz suggest any other method 4 backing up the rom and custom recovery...
