Hey, It does feel really comfortable and very loud. Also, the thinner-fold configuration Steven mentioned seems to allow a smoother transition to another mode (dunno what it's called yet). Apocalypse Please by Muse has lots of fairly high overdrive with these vowels so that should be fun to learn.
There is some sort of hold in compressed neutral. Assembling the vocal chords and making a click sound (I can't actually do the click sound). Maybe it's that or edge.
I'm still not sure on curbing but I'll try what you said tonight.. THANKS!
EDIT: eggplantbren: I tried taking the sound higher and it's working... this feels great. It's so effortless and weird I'm starting to think it's not overdrive. This made my week.
