After 45 years of storing cigars in various ways within my sink-cabinet-size humidor, with and without cellophane, separated and mixed within the boxes, etc., I will venture to say that (with the exception of fire-cured tobacco and gross aromatics) the flavors and aromas just don't seem to mingle, even with naked cigars laying side by side for many months.
Cello is perfect for selling individual cigars, and maybe for carrying them around in the absence of a good cigar holder. But I would be happy if every cigar sold by the box were left without cello (or a band, for that matter). Cello might be essential for extremely fragile wrappers, but I seldom have those.
Bock y Cia., back in the 1800s, invented the cigar band as a tool to minimize counterfeiting of their brand of cigars--at a time when naked cigars were sold from store counter tops out of open boxes. They're nice when you give individual cigars as a gift. Otherwise, I find them as annoying as the "safety" seal (read, "lawyer's seal") on a jar of peanut butter.
Now, doing experimental home-blending may benefit from a band of sorts, simply to record the blend.
So, I persist in my mantra. Simple works.
