I'm a cinnamon freak too! Baditude gave me some really good advice on glass tanks. I love my vivi mini nova, but while the tank was ok, the cinnamon affected the threads around the top where the cap screws on. I think the full sized nova has metal threads (although I could be wrong), in which case that might not be a problem.
ETA: I looked at the metal tubes for the mini, but I like being able to see the juice.
