There are roughly 500 flavors out there that could be classified easily as decent depending on your preferences.
Before you place your first DIY flavor order, you might want to order only those flavors you will need to make 3 or more recipes. Order all the flavors for those recipes. Very few (2-3 flavors out of a 50 or more can be satisfying as single one flavor mix) flavors can standalone.
If you cannot come up with 15 flavors in your recipes, you can choose some enhancers such as:
TFA Acetyl Pyrazine 5% PG (When ordering, 10-15ml. is plenty to start with)
TFA Ethyl Maltol 10%
A Stevia/Sucralose Sweetener
