I can't stand Mountain Due. I have had a hard time figuring out why it's so popular. Jones is very good, with the possible exception of their "Holiday Specials"... Turkey and Gravy soda?... I don't think so.
I also love Thomas Kemper Vanilla Creme and Orange Creme soda. However, Coke is what I usually buy due to availability and price.
By the way, did you ever get around to dissecting that Bose cube?
