Ooooh, R_M, this was mentioned in the comments of the blog in the signature below this post (article on reformulation). In my view, a 'non-hobbyist "normal"' person probably *would* be satisfied with the reformulation, though there really is no doubting that it has been tweaked. What persuades me is the fact that you say your mum generally likes soft florals -- I find the new MN far less pungent than the older stuff, and wonder if this is because its civet component has been recalibrated. It does, however, make the scent a little 'sharper' in one aspect, to my inexpert nose. (Contradictory, moi?!)
Having said all that, VM I Hate Civet reckons the new stuff is more civetty than ever ... so there you are! Even more contradictions to contend with! Though hopefully a few perceptions for you to mull over.
