Welcome from Ottawa, Canada, where Black Dragon wrappers smell like they have been coated with some spices.

1. I don't think so.
2. Some cigars don't age in a linear manner. For example, some Cuban brands are known to go into "sick periods." I don't know anything about Visions, perhaps smoke one every few months and see what happens?
