The term "navy flake" is rather amorphous. Most of them contain some Perique, while others are a jumble of components. Cornell & Diehl After Hours Flake is about as pure a navy flake as you can find. This is a straight Virginia flake that's naturally sweet, enhanced by the addition of some dark rum. If navy flakes are your bag, C&D's After Hours Flake is as pure an example as you'll find.
