So I've read a few things about cinnamon juices around here and it's gotten me a bit nervous about putting my Apple-Cinnamon juice in a clear carto. Anyone have any problems using cinnamon flavored juices in their clear cartos? Mine actually has very little cinnamon in it. Probably not even half of the juice is cinnamon. I've only had it in the black cartos upto this point but now I am just about out of those and have only the clear ones. Wanted to get some feedback before I tried it. Thanks.
