Anyway, here's what I've done(well, kept) so far: Arconium rom as I prefer t.he SE ui over generic launchers, link2sd to basically expand internal memory, juwe11s ram optimizer, Doomlords kernel with overclocking at 1.6ghz which is fast yet stable, se home 5*4, the obligatory ics theme, a few sysctl rweaks, a few build.prop tweaks and that's about it. I can get huge quadrant scores with cm7 but I don't really judge by them, they're a bit like 0-60 times for a car... That's what I have at the moment, and have decided(so far)that these are the best options for me.
