Touchwiz was your problem and you got rid of it so it shouldnt get slugish. I ust Flux as my favorite theme for CM12.1
I really like Flux https://play.google.com/store/apps/details?id=com.flux.theme.flux
Flux is one of my favorites and is updated fairly frequently. Check out the dev's other themes, too.
I'm into Flux at the moment.

This theme has a very light font. I'm pretty sure it's used in other themes as well, but that's the one I know.
It's like flux icon pack but with white circles? https://play.google.com/store/apps/details?id=com.flux.theme.flux&hl=nl
I can't find the exact font but it is a sans-serif font. I got it from the Flux theme on Android
