152 ... does that count this post or would this be 153 ?? ... wow, indeed!!
Cello Off ... they do age better, quicker, but can suffer damage to the wrapper easier than w/cello on. I used to take the cello off every cigar.
Cello On ... cello retards the flow of moisture, in to the cigar as well as out from it ... BUT, it is not a vapor barrier ... over time, the cello will make little or no difference. It will, however, serve to give some added protection to the wrapper ... I've been leaving cello on lately as an experiement and almost half my cigars have cello on ...
As for flavors 'marrying' ... a VERY minmal consideration unless you're talking about actual flavored cigars in which case cello won't do the job ... you need a completely seperate humidor (although IMHO, giving them to someone who promises not to smoke them upwind from you is an even better solution) ... never buying flavored cigars at all is the optimum method of dealing with them.
