Maybe it's just all in my head but when I had CSSU installed, I had little issues and my phone felt more slower. So I've reflashed fresh and now just run without CSSU and with power kernel v46 overclocked at 1.1Ghz. (which I was running before anyways) It's never been more stable and responsive. For the past month, I never had to reboot once except to dual boot to NITDroid.
