Giving this some more thought....there are so many snuffs out there it is hard to make recommendations. My main recommendation would be to get a variety of styles and grinds.
Coarse is good for learning how to snuff without getting tobacco in your lungs. But for me finer and dryer causes me less nasal problems.
My favorite producers are Toque, Wilson's, Samuel Gawith (who everyone feel makes the Viking line). Another favorite of mine is FUBAR Grunt.
