Snipe, you can and will drop to 3mg if your dripping IMO, which if you think about it one cigarette = 0.8 mg so vaping 5mg of 3 or 6 to me is way better than the pack in a half a day I did last year.Try the flavors that you use to dip, wintergreen / tobacco ? you give me the profile and you will be vaping it.I personally loved smoking cohiba cigars so I still buy them and do cold maceration's with the cigars and vape it on a dripper, kinda nice when my cigar smoking buddy's come over.
Mike I like those ratio's and those profiles but you might try a regular TFA sweetner instead of the Ethyl Maltol to me it makes my flavors fade within 30 days or sometimes interrupts, you need it with the candy, chocolate type or lacking body mixes but not so much with the custard's your vanilla / sweet cream is a good sweetener as is, I usually do the 4 drops per 30ml and you can taste / feel it.
I think that recipe you just put out would be better than most vendor bought add 4 drops of creme brul'ee ?, if it's not nutty enough add a few drops of Acetyl Pyrazine.
