I ended up flashing this today. I ran it since this morning.
I like it alot. The themeing isn't over the top, it has quick settings that you access by touching Tranquility in the staus bar, Volume rocker to skip songs.and a few other things.
The only problem I had was I couldn't switch my Keyboard so I flashed in the IME switcher that the have in the OP of XDA.
I'll have a better gauge of battery life after a day or two.
