Maybe I just had a dud but the Flor De Las Antillas I had dissapointed me. Draw was way too loose, no resistance at all. Flavors were good but not fantastic.
Probably the most frustrating cigar for me is the Alec Bradley Tempus. I like the flavors a lot but it seems like every 3rd one has horrible construction/burn issues. I got a several on Cbid from the free fall almost two years ago and they will nap for a long time at a lower RH (63) and hopefully fix some of those problems. You never know.
