I have the same problem. I have found even though it is the other side of FL from me lol the vapor store I got started at has a couple flavors I like and they add what is on the bottle as +10 on flavor. Its Tampa Vapor and I get spearmint and Very Berry 60/40 pg /vg +10 (what the label says)
They have other flavors that others love but I don't get good results.
Also, don't throw out your bottles that have no flavor they just may need to sit for a week or two then try them again. After that I trade them with people I run into that
vape. They get out their pile and I drag out mine .we taste test and trade.
Everyone's tastes are different what I may like you may hate.
Good luck and don't give up!
