Don't get me wrong, these are both beautiful flavors that i use regularly in my mixing. But if I were to try any one of those flavors without knowing what they were then my first guess wouldn't be vanilla. Which flavor gives that pleasant and obvious vanilla sensation? TFA or CAP vanilla custard? French vanilla? Vanillin?
And yes I understand i could go off on a whim and buy a bunch of sample flavors but i like to cut to the chase.
Myself I use a mix of Capella's Custard V1 with TFA French Vanilla, Capella's Marshmallow for the sweetener. I let mine sit for atleast a month if not 2 and it turns out very nice. I don't speed steep so with these flavors I found that the longer you let them rest the better they are. % will be up to your tastes but I think you would enjoy the out come.
I use a blend of French Vanilla(2%), Bavarian Cream(2%), and Vanilla Bean Ice Cream(4%) plus a little Marshmallow to sweeten(1-2%). Let it set for about a week. Vape and enjoy. All TFA
TFA French Vanilla at 10% with 1-2% Bav Cream and 1-2% Marshmallow also works well.
Wouldn't suggest mixing the V2 with V1 flavors though. Some interesting research coming out about Butyric Acid increasing Diketones or something to that effect. Either stick with V1 or V2 don't mix the two.
Tfa Bavarian cream also couples very well with the tfa vanilla swirl and the tfa sweetener. Also try some ry4 double in their, it's not so much tobacco as just a deeper dark vanilla flavor.
