I'm going with My Freedom Smokes RY4. I've tried puresmokers, DIY and DeKang RY4, but MFS has the best in my opinion.
PS = sweet caramel vanilla flavor
DIY = Yummy caramel with a slight fruitiness
DeKang = smokey with a drop of caramel
MFS= smokey base with overtones of caramel and vanilla and an undertone of sweetness (sort of like cotton candy or some kind of fruit)
