Basic support/add on flavors
TFA/TPA Dairy Milk is nice for creamy fruit types & also good for adding to Ice Cream.
TFA/CAP Vanilla Bean Ice Cream, good base for Ice Cream.
TFA Vanilla Swirl (Creamy Vanilla)
TFA/CAP Sweet Cream (Dairy Milk seems better for me)
TFA Cheesecake Graham
TFA Brown Sugar
INW Shisha Vanilla (one of the best Vanillas IMO)
INW Biscuit for cookies & works great added to most anything
FA Marshmallow (adds a hint of sweetness and body to most anything)
FA Coconut (adds some buttery effect when used in small amounts 0.5%)
CAP Vanilla Custard v1 (best one for custard vapes)
CAP NY Cheesecake
If you like fruits...
TFA Blueberry Wild
FE(Flavors Express) Blackberry from ECX
TFA Orange Cream(A bit like Orange Creamsicles)
or CAP Sweet Tangerine(not really that sweet IMO)
Some like TFA Strawberry Ripe, (but I prefer INW Shisha Strawberry way better).
INW Waffle + FA Maple Syrup with Blueberry Wild for Blueberry Waffles.
FA Fuji Apple
FA Lemon Sicily
INW Lemon Cake
INW Peach + INW Mango (better than most others IMO)
Probably missed a few
