Big fan of the Francisco (corona - lots of flavor) and Papagayo (robusto grande). To me, the original San Cristobal line is medium- to full-bodied. With a lot of Pepin's smokes, there is a big blast of pepper and spice right off the bat, especially for the first 1/2" or so. They tend to mellow and smooth out some for the rest of the time but, the spiciness is still noticeable throughout.
The Seleccion del Sol isn't bad. These seem to have less strength than the original and are more medium in body. I prefer the original series to these.
