Well, you'll get 7000 different suggestions here....
Sweet and pungent: Red and Black from McClelland. Ridiculous.
Sweet and mild: Either Capstan
Sweet and sour: Brunello from Savinelli
Sweet and earthy: Gawith stuff - Full Virginia Flake, Best Brown Flake
Right dead on down the middle of the virginia spectrum: HH Pure Virginia from Mac Baren (can't wait to see this one in ten year's time... yum yum)
