The best tobacco like taste I've found is Halo's Torque56. Next in line would be Halo's Freedom. They are having a special in the supplier's forum.
Now I have heard good things about Backwoods Brew, but have never tried them.
I make most of my own
juice and think my tobacco flavors are pretty good, but I still buy Halo and still use it. It is a bit higher in cost than most, but it is good. And those blue glass bottles and well marked dripper are nice too.
I'm sure others will have tobacco like flavors that they like over my suggestions.
I really think that the
juice is the real key to making the switch and finding the right
juice for the individual is the toughest part. Hardware is easy.
