I am sure it has been mentioned... But get the menthol crystals on ebay. You can even put them INSIDE the cart.... I'm telling you... You know those guys with the subject "Please help me looking for newport flavor"... This is how. It is just that simple.
Some claim it is the PH levels of the liquids... Hence why Johnson Creek puts in lemon juice in their eliquids. And then there are some like me, who feel sometimes a good throat hit is because your burning a little bit of the polyester fiber in your cart. lol just kidding.
I have head excellent things about the dragon. I have watched it in action via teleconference and it certainly produces more vapor then other 401's I have seen. Some say it is great for "dripping"....
