When I resorted to a pipe (mainly smoking cigarettes), I'd settled on Three Nuns and usually had a bowl in the evening. Then Three Nuns morphed and morphed again and I stopped enjoying it, then got well into latakia and English/Balkan before drifting to virginias and then VaPers - kind of full circle. Not hugely into burleys, though maybe I'll discover that attraction yet, not that I've completely abandoned any of my previous loves.
Aromatics are beyond me, for the most part, although finding the real tobacco taste under the disguise is pleasing.
In parallel, cigarettes gave way to RYO, which is barely a convenient nic sideshow these days, very few.
Oh, has my palate changed? All the time; mostly, revealing new angles on well known smokes.
