[Q] F2FS How to? topic

Hello guys.
Google couldnt help me :confused:

I want to test f2fs on our device, but I dont know how to do this. I cant find a twrp 2.8 recovery...
So I have two questions:
1. How to switch/reformat the filesystem (for example with greatdevs kernel)?
2. Should I do this? (I also read it might be unstable :confused: )

Thanks guys! :)
