Welcome to the forum and to vaping! The world of flavors awaits and you will have lots of fun trying lots of different kinds. I have some favorites, but it is all a individual taste.
Caramel and Butter Rum are very good. They are usually blended with other flavors. Apple and Caramel is great. I tend to like those better than the fruit flavors. A Caramel tobacco is nice. The Cream type flavors give a good body to the taste. I also like the Nut flavors, pecan, and pralines. Oh and almost forgot Maple flavor is great blended with tobacco, or something like maple & pecan.
