I've been playing with pear flavor recently:
-Pear, Dark chocolate, Dulce de Leche, Vanilla, Rum.
-Pear, Dark chocolate, Apple Pie, Bavarian cream.
-Pear, Coconut, Vanilla, Lime
-Pear, Coconut, Vanilla, Bavarian Cream.
Not much use for me to give you the % as I'm not using TFA flavors. What I usually do is have 2 main flavors which each make up 1/3 of the total flavor, and the resting 1/3 is a rounding mix of flavors.
Example for 6% total flavor in 100ml
Pear 2ml
Dark Chocolate 2ml
Dulce de Leche 0.8ml
Vanilla 0.8ml
Rum 0.4ml
