I'm a fearless (and sometimes foolhardy) Frankenjuicer and semi-DIYer. (Frankenjuicing is mixing finished juices together (usually retail juice), while semi-DIY is adding some flavoring concentrate to an existing retail juice.
I don't generally alter 30ml bottles of juice. Safer to do my experiments with small sample quantities. If I ruin 3mls of juice, it's no big deal. Wrecking a 30ml bottle is another thing entirely.
To my straight NET tobaccos (mostly from GoodEJuice's house-extracted line), I might add a little (or sometimes a lot) of a wide range of non-tobacco juices: various vanillas, different caramels, nuts (not generally peanut, but pecan, walnut, cashew, pistachio, etc.), fruits (banana, pear, apple, although not generally any of the berries---strawberry, blackberry, raspberry, blueberry), honey (in tiny amounts), malt, cream, liquors/liqueurs, etc.
I also experiment in the opposite direction, sometimes adding a straight NET or good synthetic tobacco juice or flavoring to dessert juices to give them added body, depth, and bite.
I've been going through a phase recently of adding varying amount of different vanilla cupcake juices to tobaccos. Yum.
And through it all, I still like everything as-is: straight tobacco, tobacco blends, non-tobacco sweets/desserts, fruits, etc. Can't have too many different combinations to suit whatever mood I'm in on any given day/week/month.
