My neighbor 3 houses down only smokes Captain Black Gold, I asked him why doesn't he try other blends and he said he likes his Captain, he is over 70. My dad only smoked Macanudo Prince Phillip cigars, I would bust his balls unmercifully about it and he would just laugh at me. He would tell me to stick my Cubans up my ass, but he always bought me a box when he traveled over seas. I would get him to try something different maybe once a year but that was it, he loved hiss mac's even though he could afford any cigar on the planet.
I cannot imagine smoking the same blend day in and day out, I would rather quit than do that. Variety is what I like even though my rotation( 16 or so) is small compared to some. I am still always on the lookout for a new one to add to my rotation, you never know when another favorite might make it in to full time use.
