As a bit of an old timer in this flake game I have never understood the stuff and go method, rubbing it out is the way the blenders of the flake tobaccos intended it to be prepared. Let's keep in mind the original purpose of the flake form of tobacco production was basically twofold. In the early days of sail sailors would buy bulk pipe tobacco and press it together as tightly and compact as possible to be able to pack it into there tobacco bags so as to take as much to sea as possible in a small space. This tobacco was usually Virginia leaf with a tremendously high natural sugar content so the unforeseen advantage of this putting the tobacco under pressure literally forced the natural Virginia sugars out of the leaf thus reflavoring, if you will, the tobacco with its own sugars. That is why you find sugar crystals on well aged Virginias like Gawith's Full Virginia Flake, that sugar is from the leaf itself, not added. If you could go back in time and find old Sam Gawith and tell him you were trying to smoke his flake tobaccos by simply stuffing the full flake into the pipe he would laugh you right out of his tobacco factory and probably tell his co-workers, "check out the guy who was just here, he will probably use an entire box of matches and still will never get our flake to burn properly" and they would all have a good laugh. Rub it out thoroughly, let it dry for awhile and then pack it using the tried and true three step method. You will get a sweet smoke every time if you puff slowly. Keep puffin.
