What Tobacco has the strongest buzz?

I chew regularly, and I have tried quite a few... Copenhagen Black, Straight, Long, Skoal Wintergreen, Kodiak, Longhorn, Redman, Even Camel Snus. I am looking for a stronger buzz without all the minty, fruity flavors. Just a straight Tobacco. I really don't want to have to take X to beef up my buzz, so I will stick with the tobacco. So far, the best one I've found for me is Cope Extra Long, but even that isn't strong enough.
