I would agree to leave them on at this point, cigars are much more resiliant with the cello's on plus it'll protect them in case your humidor doesn't have a constant RH at first, so until it levels out and is consistant for some time, I say leave 'em on!
In one of my desktops, it holds about two hundred, I have the top shelf in the Humidor filled with cigars that don't have cello, but those are for my patio only and won't be traveling anywhere....
Plus I just like the look of my humidor when I open it...naked cigars neatly lined up, and the smell is amazing!!!!
