What gets me with the FA flavors is how to exchange them for other brands in the recipes I got on here. If it calls for 20% Lorann, or 10% TPA, then how much FA should I use? The first few recipes I did I just used the same %, but I thought later that maybe that's why I didn't enjoy the flavor much, went too strong on the FA (didn't think about the fact I'd need to adjust because FA is stronger). Since the recipes are made based on the user's taste, it's hard to know how much to adjust, because maybe they made that flavor strong in the first place. One could almost wish that all of the flavors were the same strength.
