First off , in all the years i have been on DIY forums i have NEVER , not a single time heard a single person say FA flavorings are weak & tasteless . FA has always had a stellar reputation for being more potent than most and their flavorings have always been very highly regarded .
Read
reviews on sites like Bull City flavorings and you would be convinced FA are perceived by many as the standard by which all other flavorings are judged, (not what i think) but to many they are.
There will always be people who don't care for them but to say they are weak & tasteless is absurd .
That comment to me is like saying a Ferrari is ugly and slow , you may hate Ferrari's but spare me the ridiculousness of saying they are ugly and slow which is as ridiculous as saying FA flavorings are tasteless and weak.
Now you were wondering how to decide with all the choices , this is what i have always done :
I do most of my shopping at Bull City Flavors , the customer feedback is excellent and i rely on it to guide me in to choosing the flavorings that get the most positive
reviews and i have not been disappointed.
I have never just taken chances with flavorings , i know what flavors and recipe types i like and will make the most of and i target those types of flavorings.
I think most start out slow and over time build their collections of flavorings up.
I always buy 10 ml sizes before i buy larger sizes and if i really like the flavoring i will buy larger sizes in the future . Everyone ends up with a few dud's that they don't particularly care for , part of the process.
If you have to buy 10 different Blueberry flavorings before you find the right one something is very wrong , read reviews for the different Blueberry choices and it will come to you , i would also Google best Blueberry e juice flavorings .
Hope this helps
