RY1- Real strong flavor. Lots of people describe it cigarish, pine, smokey, salty, robust... One of my favorites
RY2 - Pretty much the same as RY1 but mellowed out a little... Smells a lot like salty tortilla chips to me.
RY3- Mellow
tobacco flavor with carmel, vanilla, toffee undertones not nearly as dry as RY1 or RY2... Tastes a lot like DK TAB if you've ever had it.
RY4 - Nothing like RY1 or RY2. Some say it tastes like cotton candy, some say it tastes like a mellow
tobacco with vanilla or carmel overtones.
IMO RY2 is my favorite but by far RY4 seems to be the most popular.
