Lol, interesting Vaptor.
I like your deduction and I think you're right, Field of Wind is most likely aimed at being a Winfield type flavour. I don't usually vape pure tobacco juices though, they just seem a little boring to me and never even close to the flavour by comparison. So I would imagine that if Field of Wind was supposed to be a Winfield flavour, you would never know it if you tried it.
Still, if you do try it, let me know, it may be one that is worth using in an RY4 type of mix for me.
