I put this ROM on my F6 without any issues whatsoever.
Once Link2SD was put in place with my properly-partitioned 32Gb MicroSD card (30Gb FAT32, 2Gb ext4), everything went amazingly, surprisingly smoothly.
Once Link2SD was in, I started playing with Xperion's "system" apps in an effort to get the ROM to behave more stock-like, more like my N5.
For example: I installed the "stock" Android keyboard, switched from Xperion's LG one to the stock one, "un-system'd" the LG keyboard, "system'd" the stock one, then removed the LG one from the ROM altogether.
Same goes for the launchers - I installed the "GoogleHome.apk" Google Now Experience launcher - the one that ships with KitKat 4.4.2 now. With this as the default launcher, I un-system'd and uninstalled Nova Launcher.
Pretty much all apps save the critical system ones are now linked on the MicroSD second partition (/data/sdext2).
As a daily driver, compared with my Nexus 5, the only things I feel I'm missing are the Google Now integration and the panoramic photo capabilities. Performance is perceived as about equal, with my only concern being the F6's memory (1Gb) over my N5 (2Gb). Given that my N5 was US$350 and I got the F6 on sale for US$80, I feel like the F6 is an absolute STEAL once this ROM is put in place and the SD card configured.
