Hi Albe and welcome to DIY!!! I did the same thing you did and ordered a lot of different flavorings when I first started. I started out making small 5ml batches of each flavor on it's own at 10%. It's necessary to give you an idea of what each flavor can bring to the table, but when dealing with that many flavors, it gets boring as hell pretty quick. I ended up scrolling through the forums and making some recipes that were posted here that I thought I may like, and then tweaked them to my taste. I have flavors that I've had for months and still haven't tried, but each time I make juice I make it a point to make a couple of single flavoring test batches while I'm making recipes. It kind of breaks up the monotony of taste testing single flavors and gives you some good juice to vape to keep you motivated
