I agree, this is still one of my favorite topics, since it still seems so much more art than science. Plus it takes so long to learn from experience, so I am always interested in other people's first hand knowledge.
And that's really interesting about the broadleafs. With my almost nonexistent expertise I've been thinking that stronger/fuller means better aging potential.
I know you keep really good notes, so are there any standout NCs that have aged well for you, or not so well? I've got a bunch of boxes now dedicated to a 3+ year aging plan, but maybe there are some cigars in my humis that I should sample soon.
