I find myself in a similar boat. I have 30+ flavors packed away steeping. Haven't liked over half of them right out of the box (they also had rave reviews).
Tried an RY-4 from a local vendor which had an awful artificial and chemical taste. After a week and a half, it became my favorite vape. Flavor totally changed. Hope some of the others change for the better as well. Fingers crossed.
Sorry I can't be of more assistance, as I am also new to vaping. On the positive note, even with the less than stellar flavors, vaping has replaced my pack a day smoking habit. I'm breathing better, have more energy, and oh how glad I am not be sitting in a cloud of smoke! Hang in there...keep searching...you'll find something that works...it's important.
Good luck!
