I also have been migrating toward smaller RG's. I get frustrated at new cigars that come out with nothing smaller than a 52!
You may be interested in the Reyes Family Cigars Puros Indios line of Big Ring cigars. Cbid has great samplers of Viejo (6" x 60), Pirates Gold Maduro (6" x 60), Cienfuegos (6" x 60), and the Reserva Maxima (6" x 60).I enjoy a larger ring cigar very much . The larger ring allows the tobaccoes to blend in their own special way to deliver a unique flavor. Not that the flavor is any better or worse than smaller RG cigars, its just a different flavor scheme that appeals to me. If I'm in the mood for a 2 hour smoke, I'll pull a 6.5 x 54-58 out of the humi. If I know I'll only have 45 minutes to an hour, I'll pull a robusto out. I think the smallest RG in my humi is 50. I do have some MC Afrique Safari small cigars in the humi for when I'm driving 20 minutes to work. They are 4.62 x 34 cameroon. Tasty little guy.
Me too, like I said earlier, I'm an equal opportunity smoker. However I love the Gurkha perfectos and the RP vintage 1992 in the 6x60 is real good as well.The largest I have (and will ever go) is 6 x 60.
