I sort of thought they might be also but according to our Mad Scientist there's some differences in at least some of them. Favorite tobacco flavoring discussion - Tobacco flavoring discussion only | Page 52 | E-Cigarette Forum
As it happens I mixed up some of the BCV "Chinese" french pipe over the weekend. The VZ french pipe is sort of maybe very light chocolate and vanilla or maybe dried fruits (I just can't tell but tastes good to me) with what I taste as cigar in the background. Delicious. The BCV french pipe I got is also very good. Not steeped yet but solid burley and virginia blend (reminiscent of VZ real cig to me, maybe a little heavier on burley) with something sweet I have no idea what it is. Both very good but very different.
Inawera french pipe is sort of like light M type with something sweet. I don't like that one.
