It's been a long time since I smoked DF scented, and then not much of it, but I would say that the topping for DF Scented was lush, that is very full and delightful, so I wouldn't be surprised at all that it is more than just rose geranium.
I never smoked Brown Flake Scented.
I haven't seen it in awhile, but entire threads can spin out Lakeland bashing, their war cry "Grannie's panties" or "Urinal cake." But that flies in the face of the fact that Lakeland tobaccos have a very solid niche in the market because of scenting, price and quality certainly also very important.
