I’ve always considered Flakes as just a Production Method/Process, marinating flavors together differently under compression, and how you smoke it doesn’t matter.
Folded and Stuffed Flake, vs Ribbons, seems more like a preference than anything else.
I’ve folded and stuffed and rubbed out, in the end, the tabac tasted the same, the only difference being, having a folded up wad in the chamber was more difficult lighting and tamping, so I personally just rub out the amount I’m going to smoke, and let it dry a little.
Rubbed out works easier I find in the chamber, lighting, tamping, etc...
