I have not smelled the recent ones, apparently it was reformulated around 2010 or so.
I have an older one. It's a combo of violet, heliotropin (almond), and a touch of iris, sprinkled with french herbs (thyme and the like). Very beautiful and haunting, but it's difficult to describe because on the market right now there's really nothing that has the same style and feel. It will likely appear "old style" to mainstream consumers.
For this reason, it's likely not a safe blind buy. Luca Turin thinks that the reformulation is pretty much an iris soliflore, but, again, I have not smelled it.
