I too was a pack a day Marlboro and Winston Red smoker for 40+ years. I faced the same problem, trying to find tobacco vape that tasted like a cigarette. After trying several different tobacco flavors I came to the realization that when I smoked cigs, it wasn't because I enjoyed the rich tobacco flavor, Actually I taste very little "flavor" from cig smoke.
Now that I'm vaping, I can now really taste the flavor and it is WAY better than cigs. could ever be. I have been vaping for only a little over a month now, so I am no expert, but I would advise to just keep experimenting with different flavors . You will find one that you like better than cigarettes. For me it is the Halo brand, Longhorn and Prime 15. Great taste. Good luck.
