I only use tobacco flavors. I primarily use Marlboro and camel. I tried the red bull and it waw awful.
As far as regular tobacco flavors go I just can't really get into anything that comes in the prefilled cartos..
I find the best for me is a blank carto filled with juice from a different vendor...
Menthols are a completely different beast...the smilin special menthol and the kool menthol are 2 of the best menthols I've found anywhere..
