You gotta keep 'em seperated

Flavored cigars suck!

But that's just my opinion. Smoke what you like, even if it's a peach Optimo. I think if you continue smoking cigars you will begin to appreciate the non-flavored cigars more. I would find some tupperware and use that to store the flavored stuff in. I doubt you will even notice if they are dried out or not. Keep the humidor for the good stuff. You can lightly sand the inside of a humidor to remove some of the odor from flavored sticks but what a pain in the ass that would be.
