I disagree with the statement that burley is easiest. I would say it is the simplest.
Re. "Virginia", with a more complicated curing arrangement, you can easily produce flue cured tobacco that is quite excellent. Burley is more difficult to grow, requiring more heat and nutrients, and takes up more square footage and time while curing. Burley needs more aging as well.
Also, I don't like this idea batted around that natural tobacco is unpalatable and must be made so via processing. Try telling a cigar producer that cigars need non tobacco ingredients in them to taste good, lol. Processing is not just about making it taste good, it's about making a commercial blend taste consistent year to year, with different tobaccos every year, via flavourings; retaining moisture levels and retail weight via humectants; and preventing mold via preservatives. Pipe tobacco processing is about making storage idiot proof.
There is amazing whole leaf out there on the market, and with some fiddling, you could easily make blends that are superior to most of the commercial tobaccos you get. Add a few tricks like pressing, fermenting, steaming, toasting, etc, you can make downright amazing stuff. Just don't expect flavored tobacco. That requires the skills of a chemist.
