Hi Chico,
You seem to have a handle on the blends that you're trying. Take note of the country of origin because it may be possible that a particular tobacco is packaged under a different brand (and that'd confusing). I taught new smokers that their enjoyment would be a combination of taste, technique and mental impression.
- Taste is self explanatory.
- Each tobacco presents small challenges to get it to perform but when you conquer it the enjoyment is heightened.
- What you expect and how well the tobacco meets your preconceptions enhances the experience.
I have no idea what mixtures are tonquin heavy beyond 1792. Full Virginia Flake has a touch. Perhaps others can weigh in on this question?
