Think I am going to mess around with blending French Pipe, Black Cigar and another tobacco, maybe Honey Flu Cured or Tuscan reserve and see what happens.
I am pretty sure though that the French Pipe, or something very similar is the main base flavor. I also have a bottle of GJ and that even more than BB smells exactly like the French Pipe and if he said he removes two tobaccos flavors for GJ then the FP is the one that remains.
I think your on to something with your tobacco flavors. I just read this review of BB that is one of the best descriptions:
"So far the flavors I taste WITHOUT A DOUBT are honey flu cured, a dominant raisin flavor(it really comes out after steeping), and a rouding nuance of sweet bold Graham Cracker. These are the three flavors I pick up. In fact, when I chain vape Boba's for days I can ONLY taste the raisin.
Now, there IS this strange and obscure almost "grainy" nuance I taste. Maybe it's a soft black tea note, or black honey, maybe even a background note of the raisin. It's like a leathery, but earthy note. I am NOT certain but it is the only note I can't 100% make an educated guess on."
