Personally, I found the custard I like, then I frequently add a little of another flavor (fruit,
tobacco, or bakery) to create a new blend when I want it. This give you the ability to have a huge range of options and personalize to your taste.
vaping Nicoticket's Custard's Last Stand plus Apricot Ambition at the moment.
Blueberry is not a flavor I have taken the time to find a good one of yet.
