Yeah I'm not sure man the Jury is still out for me. I keep a 50 count humidor at 62% RH and CELLO off. These are generally my "on deck and ready to smoke" cigars. I am by far an expert on flavors but if they meld in there...Its been a GOOD thing! Because I really really like how they have been smoking and the flavors I have been getting. Now that said I don't really taste any different flavors from exact same cigar pulled out of my storage box...
Now I know you asked about CELLO ON but I guess if my CELLO OFF no problem is any indication I think you are going to be hard pressed to get any cross flavors with them on. UNLESS maybe you are dealing with, smoke cured or infused where the flavors are really pronounced..


Cheers
