Yeah, baby! Rochas Lui blew my shoes off when I first sniffed it too. Killer. Love the stuff. Reeks of old classic style, you're right with the comparisons to heavy hitters. I thought it a fantastic variation on Habit Rouge when I got it, and I'm reminded of that when I smell it too. Very different from HR at the same time, heck I don't really know.
But you're right--it's grand. On the current thread about disappointments I was surprised to read of several members listing Lui as one of their biggest disappointments. I'm so sorry people miss out on the pleasure I get from this one.
