I recently picked up a couple of tins to try this for the first time. I love SG's Full Virginia Flake and Dunhill Flake -- as well as the Rattray's Virginias -- so I figured I needed to know this one too.
I was underwhelmed. It struck me as the lightest VA -- by far -- of all the flakes I'd tried. I knew it was a good tobacco, with good leaf, but there just wasn't much flavor/substance to it. (And I wasn't looking for nicotine here; I don't like medium-to-high nic blends.)
Someone here mentioned that it changes dramatically with age, taking on the characteristics that the OP noted in this thread. I'll have to see.
