Along the lines of what Robby said: a cigar can be mild-bodied but still be very flavorful, although more subtle and delicate. As you move up in body (medium, full), typically the flavors become less subtle and delicate, and more intense and obvious. I don't think, personally, the wrapper has all that much to do with it, other than providing it's own distinct bit of taste to the cigar, i.e., I've smoked extremely full-bodied cigars with a natural wrapper, and conversely, very mild-bodied cigars with a maduro wrapper. Again, we get back to individual tastes. Just my thoughts.........
