I think the decision really depends on where the particular brand is positioned. If I'm Mr. Cohiba I don't sacrifice my flagship's quality (ie, expected flavor profile) just for the sake of putting out a product. To another poster's point, if I had good quality tobacco that would produce a truly flavorful cigar, but is too far away from what my customer base would be expecting, I'd brand it under a different banner. I'm not sure if the Monte Cristo Open is a good example of what I'm thinking, but it is somewhere down that path.
