I see it as much closer to my natural citrus (things like Bois de Cedrat) than to my synthetic designer scents. The fair-to-poor longevity of my juice seems to betray that as well. Now I need to admit that I do like synthetic notes, and might not even notice synthetic components which don't make themselves at least somewhat known.
For me, the neroli in Neroli Sauvage is very, very dominant. I can, however, see the similarity to GIT, and would not be surprised if it is something of a citrus fougere with a substantial amount of dihydromyrcenol.
In any case, I have always considered my Neroli Sauvage to be one of my primary and most beloved natural citrus scents.
