Plugs & tight Cigars are not because of price. Torpedos are notiourios for being tight at the Cap, some brands are just packed on the tight side. Oliva come to migh. Maybe it is because they don't want to skim on the amount of Tobacco.
Price does not guarantee perfect construction, as handmade Cigars are rolled by people. People are not precision machines, no matter how good they are, or how long they have been rolling. That why Cigar tend to be different ever from the same box.
I only know of one company who has one roller doing their top of the line stuff. Padron 90th. I believe the Cigar is called. All rolled by one person, 40 year with Padron, but I am sure that person is not a machine, and even their rolled has slight inconsistencies between Cigars.
JMHO.
P.S. If you ever encount a plug, or tight rolled Cigar that has draw problems, it a reason IMHO to own a PefecDraw Tool.

Fixes problems with draw.
