Ornamental grasses for screening

I want to create a screen in my yard of ornamental clumping grasses. I am thinking about a combination of Calamagrostis Karl Foerster and either Pennisetum Karley Rose or Pennisetum Redhead. I want them to stay fairly contained and like the Karl Foerster because of its upright form but want some variety. Anyone have any advice? I'm in zone 5 and have average soil.

Thanks!
