So far this is the best rom i've tried (official cm 10.1, 10.2, pacman and this one) on my kf2 but i found a couple of bugs (very small bugs)...
1- you need to reboot the device for finding new wifi networks... I've tried turning off and back on the wifi and searching again for new networks, but that didn't work
2- if you plug the charging cord when the device is on and then you put it to sleep it will not turn the screen completly off, is like it had the screen on but with a black background... Only solution i know is to disable the option of turning the screen on when you plug a charger, then put the kf2 to sleep and then plug the charging cable...
