For me, it was the Oliva O robusto. Granted, it was early into my cigar experience; but I remember being so disappointed. Up until then, I had smoked a few Fuentes; and this one tasted completely different. I wasn't ready for that, and couldn't stand it. Maybe I'll try it again, one day; but I've got so many others in the humi, that I don't know when I'd get around to it!
