I like the ry4, I think it tastes like red man chewing tobacco, but you can taste a distinct tobacco flavor with something mixed in a bit sweeter but not too sweet more like molases.
The pipe tobacco flavor has a very strong tobacco thing going on too.
Have you tried mixing?
I found that the sweetness in PG distracts your brain from the tobacco essence of the e-liquid. I got CML liquid and it tasted nothing like tobacco never mind the real thing. I tried mixing it with green apple, the sweetness of the PG paired with the apple flavor which made the tobacco flavor more distinct and prominent, it was like smoking apple pipe tobacco.
It was way better then either liquid alone.
That's why I think combo's like
mint/tobacco
clove/tobacco
vanilla/tobacco
work well because having a flavor which is naturally sweet let's your brain justify the sweet taste of the PG, thus seperating and distinguishing the tobacco flavor.
But I would go with the RY4, it seems to be most peoples Favorite, you can smoke it all day every day, and there is no fuss mixing, I have had a few regretable flavor combos which I could net get out of my atomiser.
