My answer is that it depends on the size of your collection.
If your collection is under 50 sticks and is going to remain that way, cello can come off.
Once you start getting near 100 (or a thousand), then you will do a lot more rummaging through your cigars and transferring from one humi to another, As well as doing occasional humidor maintenance, such as moving cigars around to keep them from getting moist/dry spots in your humidor. With the increased handling that they will see, you really need to keep them in cello to prevent wrapper damage.
