This is what I have been led to believe, so your mileage may vary. Aromatics don't really change all that much during aging. Virginia seems the age the best according to most, because over time the Virginias will mellow in the blend, and a Viriginia that smokes harsh may be a little easier on the pallate when aged. Latakia tends to lost some of its flavor when aged, but the role of Latakia in the blend will determine how well it will age. For instance, if the blend is a light English with little Latakia and more Viriginia, the blend will benefit from aging as the Latakia was not the main component and you wont have to worry about it losing its flavor. Now if blend is Latakia heavy, aging it might not be the best idea, because a lot of the flavor will be lost once aged. And as far as I have been led to believe, aging burley doesnt really have much of an effect on the taste either. Hope this helps!
