Overall, I'm becoming a smaller-ring guy more and more. It's not a comfort issue (I've got a big mouth I guess, lol). There is just more character and sophistication often times. In fact, to me anything over a 48-ring is "thick" now.
The exception to this is when you're talking about well-aged tobacco (either pre-roll like the Padron 46 or simply a well-aged cigar). In that case, thicker can actually be better.
JD was saying in that interview on Stogie Review that there aren't that many lancero smokers out there. Well, I'm one of the few I guess
That said, I'm fine smoking thinker rings as long as they are on the shorter side. Even 5" is really long (I mean in terms of smoking time) when you're talking about a 60-ring. But shorter fatties are fine by me as long as the flavor is there. I love the T110, M80, anything in a petite robusto, etc. I do want to try the shortest MUWAT.
There are a couple things I DO like about large ring guages. The smoke is usually very cool on the palate, and the cigar is often smoother. But those things run secondary to flavor for me, so the flavor has to be there in any size!
