IIRC we discussed this at another place with Jon Huber (owner of Crowned Heads) and I think a rep from Drew Estates. They say that this is what the younger and new cigar smoker wants. That's why you now see so many large RG cigars. Manufacturers making what their customers demand.
Personally, as a FOG, I prefer coronas, robustos, and corona gordos. From my experience, it seems as many progress in this hobby, they tend to start gravitating toward the smaller ring gauges.
