oh, just to make things crystal clear.
I just call the techniques "fry screaming" and "falsecord screaming"
here's a quick list of other common names:
Fry - "screaming", screeching...
Falsecord - "sigh", grunting, growling, death...
note: "screaming" and "growling" are used for both techniques depending on how low it sound



To be honest, I'm not exactly 100% sure what you're trying to achieve on your mixing end, but a little saturation/ heavy compression and correct EQ have always helped me get a nice commercial soundingscreaming vocal on anything I record. So unless what you're looking for is a specific thing to the actual vocalist, then I don't know :S
