I really love Hal o' the Wynd (Rattray's), but it's not one I'd recommend to someone who's just starting with Virginias; in my experience, it requires some care when smoking in order to get the most from it.
I would highly recommend Rattray's Old Gowrie, though, as well as Samuel Gawith's Full Virginia Flake (which, despite the name, is actually mild yet flavorful).
These aren't straight Virginias, but you might also enjoy GLPease's Embarcadero (which is a Virginia/oriental blend) and Rattray's Jocks Mixture (which also includes some unsweetened cavendish), which is outstanding.
And, yes, it's hard to go wrong with a McClelland Virginia. They just seem to know how to treat these tobaccos with expert care and attention. At some point, you should definitely try Dark Star; it's a dark-stoved Virginia that is sublime. . . but it takes some work. It's a near-black flake that requires a good bit of effort to rub out and to keep lit. But it truly is a wonderful smoke. But it probably shouldn't be your first Virginia experience. I can also highly recommend the company's Anniversary, which, again, isn't a straight Virginia. . . but it's a marvelous blend.
I'm sure there are many other options out there that I just haven't tried yet. But these are a few that come immediately to mind.
Happy hunting!
