I've heard bad things can happen if you use the full modular package. That was stated in the original thread.
I took the advice of the people who dirty flashed 4.4 beta 1 over 4.3 beta 7, since a clean install didn't seem to work well for me.
I'm currently using:
05/31 stock gapps (as recommended) (Android 4.4.2)
BMS (Trinity) kernel [test kernel, 06/02. Located on Ed Chen's (GideonX's) G+ page only.] (Author: GideonX) - people on G+ said this doesn't work, but that's for whatever rom they were on. It works great on 4.4 beta 1.
PA 4.4 beta 1 (dirty flashed over PA 4.3 beta 7)
LG G3 leaked keyboard (can't forget that!)
