I revieved the samples and it is review time.
The first thing I noticed was the difference in color so as far as a blind test that is out of the question. It was very easy to tell the difference.
I took the caps off and the pour tips and gave it a sniff test. Although they smelled about the same I did notice more of a richness and more of a sweetness to the darker vape. As far as consistancy the darker vape was thinner then the lighter vape but this had no bearing on vapibility.
The all important taste test
First the lighter vape
The first thing I noticed was the maple sweetness was right up front and tobacco taste was muted. I would say to back off on the maple and increase the vanilla a smidge as I really got no vanilla. There was a sweet smokey hickory note to it which is desired in this type of vape. The flavor was rich and there was no hint of harshness. Aroma was good but sweet. You could really smell the maple. In my opinion a bit overly strong. There was no hint of wood (Who'd of guessed

)
It still in my opinion was a very good flavor combination and easyly could be an ADV (Excellent choice on flavor combination).
Now the dark vape.
This was a real treat and unique what I would consider a designer speciality vape. All the formentioned notes were there but much more blended and very smooth. The tobacco was more pronounced the maple was more of a back note, The oak woody note was very much present but smooth and mild (You timed the steep perfectly). The scent of the vapor was far more pronounced but at the same time very well blended and the scent of wood was very much present. Still the vanilla back note seemed to be missing but at the same time not needed (I am thinking that the vanilla although not detected helped in the melding and mellowing of the oakwood tone). The over all vape was more of a natural vape that you don't find with synthetic flavoring. THis ones a major ADV a real keeper. I hope you realize your first attempt was an over the top success.
This vape could be a best seller if sold retail.
EDIT: I am having a very hard time putting this one down. I may go through the entire bottle today

Every time I go back to the light vape it seems flat compared to the dark vape. THis dark vape just sings out with flavor.
