advice i've received from a gent who has been smoking 50+ years: he keeps his cigars in boxes and then stores them in tupperdors.
he opens the boxes of those he plans to smoke within a few monhts or less and keeps them propped with a stick of ceder.
he closes the boxes of those he doesn't plan to smoke for a few months and/or those he is aging, as well as all of his ISOMs.
he's probably sent me a dozen sticks over the past few months, and each one has been absolutely perfect to smoke -- perfect burn, consistency, you name it. i asked him, and he said that he'd sent a mix (those stored w/lids down and those w/lids up). he stores everything at a very picky 70% and burps his 'dors once a week.
don't know if that helps, but i'm definitely following his tips and storing what i have the same way. only difference is that anything i want to smoke relatively soon goes (single sticks) into the desktop humidor. everything else, including my one and only precious ISOM lol gets stored in a ruppador. 🙂
