Tasted Uigeadail this week. I tried A17 before and liked it very much, although found it too medicinal. The AU, on the contrary, had peatiness and sherry perfumery (which I dont' like) balanced each other (although less sherry would be better). Also, I liked its saltiness and long pungent finish, too. Anyway, I bought myself a bottle yesterday.
It costs around $150 in Moscow.
