Good question, as a relative five-year newbie, I'm still wondering. There are some blends I am glad to have cellared, such as FVF, Germain's Brown Flake, Solani ABF, HU Dockworker, and Peterson Flake. I have about ten each of those. Yet I have another 50 tins of singles/doubles/trebles, that I really have no reason to have in my possesion. Lakeland blends that I loved at first, but now feel like throwing up when I smoke them. Black cavendish aromatics that are now far too sweet and sickly. And CD blends I purchased, that I have yet to try, but can't really be bothered with, because if I do like them I can't get them anymore anyway. For all that, I haven't learned my lesson, if I taste a new bacci and really like it, my immediate instinct is to rush off and order a haul of it. Scottish Flake the most recent, I smoked a tin, liked it, ordered another four, smoked one more, and have another six on order to take me over the ten tin threshold of tins I love (or tins I love now).
