Different curing methods is a good idea. Your macro options include air curing and fire curing. With both, you can get variety by keeping primings separate, picking at different levels of ripeness, and pile curing before hanging, priming vs stalk curing, and adjusting the rate at which it cures. Rate can be adjusted by temperature and humidity. You can keep those parameters until even the stems are dry, or merely until the lamina is dry. With fire curing, the amount and type of smoke will make a difference. Each of us automatically, without intention, obtains variation just because of how it works out.
Orientals grown with close spacing and low fertilization rates are very different from the same tobacco grown with broad spacing and high fertilization rates. Maybe that affects Little Dutch, I don't know.
Topping the tobacco at a different number of leaves makes a difference. Lower producing larger, thicker leaves.
