I never did get to trying Square but heard great things about it. The Americans I did try were:
-Rooster (Potent. Very flavorful and has a tremendous bite that really grew on me)
-Levi Garrett (Only comes in these massive lifetime worth bottles. Thankfully it's really good and cheap. Smoother, smokier, and feels "fluffier" in the nose than Rooster. Really lingers too)
-WE Garrett (Tastes almost the same as the above to me, maybe a bit less smooth)
-Bruton (Quite similar to Rooster to me. But more harsh)
-Checkerberry (Great if you like wintergreen. I don't so I can't stand it. Anyone who wants a free massive supply, PM me and it's yours.)
-Honey Bee Sweet (A fantastic sweet American blend. Tastes JUST like powdered honey. Makes any
throat drip taste great)
Coming from flavored/perfumed snuffs, things like Rooster/Garrett/Bruton are going to remind you of the aroma of campfire charcoal at first. And if you can learn how to sniff them just right, you'll probably end up liking them.
I put away all my tons of snuff when I started
vaping but this
thread has made me crack open a few old tins. I'm glad I did.
