I myself am very fond of small ring gauges; perferably anything under a robusto RG. I have come to think of the shorter sizes as a testing ground for myself. I figure if a cigar can't be good, atleast to me, in the smaller sizes, then I wouldn't like it in a larger size.
For example, the Tat Angeles is a perfect size for me as an intro. to that certain blend. I would DEFINITELY smoke that in a larger size! Yum!
