Like you I started with Vanillas, and tried many different brands but for some reason my tastebuds get numb to them fairly quick. But then I tried RY4's and have been stuck on them ever since. My first was from altsmoke which was what got me hooked, then I tried dekang RY4 from a local flea market vendor. It was ok and I went through a 20ml bottle but it was a bit less sweet than I prefer.And then I tried Totally Wicked's Ry4 and that is my fav so far.
