Hello!! I'm a noob, and any menthol flavor I tried was nothing like a newport, that is my stinky of choice too. I'm not sure who manufactures Vapor Source liquid, but I bought their "new Marlboro" blend and double menthol. I've been seriously satisfied with a 3:1 ratio. 3 parts "New Marlboro" to 1 part double menthol.... not perfect, but pretty darn close. I've not actually quit yet, however, with this blend, I've had one stinky ask day so far, usually by now I'd be at four, even with my reduction from a ppd. Hope it helps!!
