Hi tarts5 I would suggest either Gustavo's kernel if you want a stable one or dorimanx's kernels which are more up to date but in beta testing yet, although I've been using the latest builds without problems. As for stweak settings I would say that they are personal and vary phone to phone. So what is OK for me could not be OK for you. Like I'm using extreme battery profile, undevolt and underclock to have max battery life.
