I bought Vanilla, Cream, Barvarian Cream, Cotton Candy, Caramel Candy, Gourmet cinnamon, Butterscotch, yellow cake, and old fashioned donut. I mixed 14% butterscotch 3% cream 3% Caramel Candy With VG base and Nic with VG base. I don't remember what others I did, I was just messing around and couldn't get any flavor. Thats when I went for the 20% Cotton Candy in straight VG base to try to get something to work. I only bought the kit from NicVape because it was an all-in-one kit.
Cotton Candy is usually just EM, a type of sweetener/enhancer, but will cause flavors to fade if using too much.
One of the reasons many here, including myself, don't like most of the kits.
Without knowing what brand flavors they are we're shooting in the dark.
As an example (FW) Flavor West Butterscotch at 14% stand alone is pretty good IMO.
The Vanilla, Cream, Bavarian Cream, & Yellow Cake you won't get much taste from as they are add ons, or mixers.
You may get something from Caramel Candy stand alone at 10-15%.
Or the Gourmet Cinnamon, maybe start at 7%.
Put a drop of flavoring on your finger to taste the strength.
PG carries flavor better than VG so you could add some PG in your mix, like 70VG/30PG.
Shake both flavorings & NIC well before mixing anything.
Takes a little time for flavors to blend in with the VG also.
As a side note:
Fruit flavors are stronger in flavor and are better for starting DIY IMO.
INW Shisha Strawberry 2%
INW Peach 2%
INW Mango 2%
TFA Blueberry Extra 7%
CAP Sweet Tangerine 7%
FA Fuji Apple 2-3%
FA Cookie (2%), or INW Biscuit (1%) are nice to mix in with the fruits.
