Rolling my own. Not only is it a hell of a hobby but I've become obsessed with what character each tobacco has.
What sensations they create on the palate, what flavors particular combos create, what strains have more body, which strains are more potent. I feel like I could have never understood these things the way I do now if I just smoked commercially made cigars. Getting my hands dirty and experimenting has been an obsession that's taught me a lot.
