I use a variety of sweeteners. Each does different things to different recipes.
Sucralose: You can get it pre-diluted in PG from various DIY vendors or you can get crystals that you dilute yourself. Good for fruit recipes.
Ethyl Maltol: You can get it pre-diluted in PG from various DIY vendors or you can get crystals that you dilute yourself. Good for bakery and
tobacco recipes.
TFA Honeysuckle: It has an earthy, lightly perfumy flavor that compliments citrus and tea recipes well.
TFA Brown Sugar Xtra: I've been using this a lot lately in my RY4 variations.
EZ Sweetz: It's super-concentrated Sucralose. Good in fruit and candy recipes. Free (sort of) sample here:

FA Whipped Cream: It's not as sweet as the above examples, but adds a lightly lactic creamy sweetness. Good in fruit, tea and coffee recipes.
