Grimstone just doesn't do it for me... Sounds like a jewel instead of a band name.
Terminal Crush - sounds like a purely techno internet band.
Unconscious Thought - sounds too Emo'ish to me.
Emotical is the clear winner! (BTW: my suggestion holds more weight than most other people!
I've played guitar and bass for 8+ years - and drums for 4. Been in numerous bands. I'm also naturally creative as I am a designer!)
Trust me, emotical kicks ass
