My personal definition of an aromatic is a blend that is some combination of Virginia, Burley, and or Cavendish (sometimes just straight Black Cavendish) with a heavy flavor casing. Usually it's a cherry, chocolate, vanilla, or some kind of fruit flavoring.
Those are the ones you should worry about ghosting a pipe.
English/Aromatics like Frog Morton's Cellar I wouldn't worry about. They're usually just cased with a spirit of some sorts, usually rum, which doesn't do much in the way of ghosting a pipe.
Deep Hollow however I would worry about ghosting, because it's just a few different types of Virginias with an apple and vanilla flavoring. Sounds like this one will be more heavily cased and will probably end up ghosting a bowl.
