The difficulty I find in your initial question is that "favorite viso" depends on what else will be in the cigar. What percentage of the viso? How much of what ligero? How much of what seco? What will be used for wrapper and binder. How large a ring size? How long a cigar. A single "favorite" viso is, for me, an unanswerable question, when there is no blend context.
I do understand your motivation for asking. Perhaps a better question would be which viso variety is most versatile in numerous blends and cigar dimensions and assorted binders and wrappers.
