My general thinking has been that flavored cigars, such as Acids, will impart much more of their flavor and in faster time frame than anything else. While I think we can all agree there has to be at least a certain degree of transfer from one stick to another in the same humi over time. Whether it's enough to notice is another question. I know that I personally wouldn't be able to tell the difference at the moment since I'm still a relatively new smoker. I have the rockets in a seperate humi and also have my treasures in a seperate humi from my everyday sticks.
