ToqueUSA Whiskey & Honey is the top 10 leading high strength snuff in the world.  After that try Artisan Oriental Extra and JP, all contain Rustica.  Next are the Otto and Artisan ranges, these both use stemless flour; which is the next strongest base for snuff.  A lot of people know about these but there is also J&H Wilson M.E.D. No99 that also uses stemless.  If you use the search box at the top of the home page it will show you the ones to try.
