I was a cell off guy, but after about 4 months of smoking/buying/collecting/trading, I've found out that I'm better off with the cello on.
1) Prevent damage from shipping cigars -- scratch on wrapper while shipping (I wrap the de-celloed cigar a sandwich bag to prevent that).
2) Prevent damage from moving the cigars -- acidity in the hands may ruin the cigars, and I know it's not that big a deal, but I just don't want my cigars to ... taste like my hand 😛.
3) I have boxes of cigars that I store in the cooler, and it's a pain in the neck to de-cello all the cigars. Besides, I keep the shrinkwrap on if I'm not going to smoke them.
4) I don't want all of my cigars to taste the same, and I know "marrying" is a debatable topic, but just want to prevent that. If I have a Connie that has the same smell as an Opus... then ... 😛
5) I keep my coolers at constant 73% humidity, so they will not dry out. I have a dry box set aside, and I have about 25 cigars in there at all times. In case the cigar is too wet, they'll have some time to dry up for a smooth draw.
6) I know cigars need to breath, but it always feel nice when I see a very yello cello, and that just tells me this cigar is ready to smoke!! 😛
Just my 2 cents.
