IDing scents?

[telophase]

I've got three new bottles of Chaos Theory III, and naturally I can't place much of the notes I smell in them. If someone who's fairly decent at IDing scents is willing to try, I'll decant about 1/4 imp of each for you to try and report back to me on what you smell. :) (First come, first serve. :D)

There's one that's especially driving me crazy, because it's a familiar scent, but I just can't place it.
