I really enjoy smoking these Partagas Robustos. My only complaint is the length is a bit too short. The Partagas Naturales appear to be the same as the Robustos except with an additional inch and .20 cents per. When it comes to naming conventions for cigars of the same brand and blend (Corona, Robusto, Toro, etc.), are they basically just referring to the length and/or dia.?
