I don't think I've ever had a single favorite smoke (cigar wise - the bad ol' days of smoking cigarettes don't count

).
I have always had favorite marcas, and preferred vitolas within those, but never a favorite I'd smoke over and over again. Just certain flavor profiles that appeal to me.
What I really enjoy about cigars is the journey of discovering which ones I like, which ones I don't, and stocking up accordingly so I always have a nice selection of the good ones to look forward to. It's hard for me to pull one out of the humi today that I don't enjoy. It's taken awhile to get there.
And really, nothing is better than firing up something you've overlooked, avoided, or rejected in the past and finding you've just discovered something else you can add to the
good list. The hunt never really ends.
