I have recently made a couple of Vader's phrases into lock-up sounds, namely his breath, "I am your father" and "Don't make me destroy you" phrases. I even made two versions of each - unmixed and mixed with default Obsidian hum sound to keep it more realistic. These are made publicly available, so I think those of you who have trouble registering can get them as well, if not, I can give you a direct link, just toss me a PM.
Please let me know what you think of these, I'm planning to make some more in the future
