I'm surprised Heritage doesn't get more attention here in the community. To me it's a very classy and Gentleman like fragrance. You are right abouth the woody an semi sweet part. But it's not a sweetness which is cloying at all. It's a sexy sweetness. In my opinion this scent is ideal for the colder day of the year. I like to wear it to the Opera or an evening out in a classy bar.
I bought my Heritage directly in the Guerlain flagship store in Paris. That was a experience of it's own. Obviously I payed much more than you have. So you made a very good deal there.
I hope you gonna appreciate Heritage as much as I do.
Have fun exploring
