However, I will point out that I do regularly hear 7-8 minute Tool songs all day long on my local hard rock radio stations. The classic rock stations are also quite fond of the super-long Led Zep, Pink Floyd, Doors, stuff too.
That's radio, though... and Opeth won't get on the radio because of the growling - unless they decide to start playing cuts from "Damnation." It just seems like radio ignores any bands that are even remotely close to extreme metal. About as heavy as they go is Disturbed.
Sounds like you have a cool/interesting job!
