Put it this way. If you swapped the two beers, which do you think would be more in demand? HotD KH or Goose Island AftW? I'd put my money on the latter. I don't agree with the volume argument, either. There are way too many variables that go into determining fair values when throwing volumes into the mix. Ingredients, aging, etc. This is why I think people should just focus on trading good beers at $4$. That seems to be the simplest way to look at it. Add all of the other factors, and things become way too complicated.
