I think this is why it is imperative for us to know what brand of flavors they are using. If we are able to crosss-reference our previous dislikes and connect them to certain flavorings from certain brands, then we may not have to travel down that road twice. That would also free up our sense of adventure if we see a similar flavor that we previously disliked, but are able to see that the vendor does not use a a certain brand of flavoring. If you hate Perfumers Apprentcice, but don't know it, you will inevitably not know why certain separate vendors are both "creating" flavors that turn you off in the same way.
I agree. one thing I believe makes me not like a liquid is koolada. but that is just a guess on my part. there are some vendors who don't have any liquids I like and it seems logical that there is some common denominator. I think there is an (old) thread here that tries to figure out what some of us don't like.
