If you like some of HHV's tobaccos you might want to look into doing some extractions. I've done cigars, Snus and pipe tobaccos all with good results. The pipe tobaccos have been the closest to HHV so far for me. They aren't clones by any stretch of the imagination but they are closer to the flavor profile than the cigars and Snus. The bases are so good that I've been vaping them for a while, just now starting to add some other flavors with them. There is a whole sub forum above for tobacco extractions, it wasn't near as complicated as I expected. I enjoy it more than DIYing with flavors and I've had better luck with it (probably because I like doing it more). I've been using syringe filters as a final filtering step but I'm gonna get a better setup where I can pull a vacuum on a flask below the filter. The better you filter it the easier it is on attys.
