Sorry for getting your thread off-track Joe, that happens a lot around here.

I honestly don't really know other than what I told you about two lines of cigars I smoke fairly regularly.

Here are some other experiences I've had:

Añejos, which come in a variety of vitolas with ring gauges between 46 & 55 all taste the same to me.
Padron 1926 all taste the same to me regardless of their length or ring gauge, same with the 1964 Anniversarios.
The Davidoff Anniversario line only has three different vitolas, the #1, the #2 and the #3. The #1 is milder than the #2 which is mild to medium and the #3 is medium to full. They are all great cigars but they vary significantly in strength and Davidoff does this on purpose with this line. Davidoff's Millenniums to me all taste pretty much the same but my favorite in the line is the Lonsdale because it just plain seems to smoke better and taste better than the other vitolas. That could be purely psychological on my part.

A general rule is that a smaller ring gauge in a certain line of cigars will be stronger than a large ring in the same line (as I mentioned earlier about the Opus X) however that may not always be the rule. I have also experienced many other low to medium priced domestic cigars where no mater what length, shape, size, ring or vitola choice there are in a certain line, they all taste the same to me, the Toraño 1959 Exodus line comes to mind first in that regard same with the Hoyo De Monterrey Excaliburs.
