I've smokes spares (in fact, have some on now, st. Louis style), BB's, butts and briskets, but one of my friends made dinner for a group using country style ribs. I don't even know what they are or what part of the pig they come from. While some of the guests found them to be highly fatty and dry, I ended up with a decent piece and thought it was pretty good. What are they and how do they compare in your view to spares? I presume they are inexpensive.
