So I'm just starting to look into the F2FS format for the N7 since everyone is just talking about it and the speed increase, new life, it gives to this great tablet. I have a few questions...

I'm currently running the following
File Format: ext4 all partitions
Rom: PA 5.0
Kernel: M Kernel a74

I've read up that PA does not support F2FS, and if you want to format to F2FS the user would have to change the rom themselves. Is there a simple way to go about this, as I do enjoy using PA.

2nd, I know m-kernel supports F2FS, do I just have to flash it and it works out of the box, or do I need to do some sort of setting?

3rd, Some people say they just format cache into F2FS, if I do this, can I still use PA 5.0 without changing the rom?

4th, Is the performance noticeably different between just cache in F2FS VS cache/data in F2FS? I assume if I format data into F2FS PA will have to be modded to run F2FS or flash another rom with F2FS support.

5th, Dumb question maybe, but why does everyone say not to format system into F2FS?

Thanks for any insight!
