Donv,
My favorites for pure VA tobaccos are Capstan Blue (#1 for me), SG's Full Virginia and Best Brown Flakes, Synjeco's Bad Nun.
There are several other excellent tobaccos out there but usually most blends are more or less mixtures (not that it would be a bad thing, it's up to your tastes)
SG makes several great not so pure VA blends, as does Rattray and JF Germain & son as well.
