I've smoked a lot of Erinmore Flake (EF) and pop a tin for the rotation as the mood suits me. I found the Erinmore Mixture a totally different blend and did not like that.
While Erinmore Flake does have a, shall I say, more aggressive topping than any of the flakes I smoke (none are aromatics), like the Sothron and Uber, I like the change of pace.
I do taste sweet fruit, but it's not overbearing and certainly not like Juicy Fruit gum as some reviews claim. It is most definitely not a Lakeland, has no Tonkin essence, it burns clean and dry and does not ghost my pipes.
As to whether it ghosts the mouth or not, while I've never experienced it from EF myself, I can see that happening to someone as we're all different and some have a more astute ability to taste flavors long after finishing a bowl. I think every puffer retains a certain lingering aftertaste after finishing a smoke -- for me, a good mouthwash seems to help when I want to get rid of it -- but I usually like it lingering on the tongue.
