I'm running Bugless Beast 1.1 with Adam Z's 1.0 Kernel at 1.1 GHZ. Other than crap battery life the phone is running great (about 15-16 hours total). I've had one freeze where I had to do a battery pull, but that's about it. I dont know if this affects phone performance but I'm also running the Smoked Glass V2 theme and some of the High Res Blue Metamporph theme put together by mjones1052 for some of the icons in the status bar.
For the first time since I started tinkering, I'm pretty happy with the setup. So obviously, I'll have to tear it apart and start over
