I like the first two. They seem a little complicated, but if you simplify it I don't think it will look as good. The only thing I noticed was that it almost looked like the girl scout cookies logo
besides everything that has been said, test that logo on a minimal scale, say for a card or something, looks like you r going to have problems there, it will look like a dirt or something, but thats just me wondering, do the test and let us know.
Hope that helps.
