I thought Flavor West's tasted like cheap gumballs. It's not terrible, but I wanted pink bubble gum.
TFA's tasted like Juicy Fruit to me, until I got their Juicy Fruit flavor. Neither one tasted 'pink' to me, seemed like too much banana.
I tried a couple vendor liquids, long ago, and they also were more like Juicy Fruit than pink bubble gum. The only supposed bubble gum I haven't tried is Inawera's (Donald Bubble, I think it's called).
In eventually just made my own. It's only 4 ingredients and tastes just like I wanted, like
a hunk of the pink stuff that came in little cartoon wrappers: http://vapingunderground.com/threads/hics-pink-bubble-gum.18233/ If you have vendor gum flavors, the details there might help you "fix" them, but I found it simpler to mix it from scratch.
(If you want Juicy Fruit instead, FA Tutti Frutti at 2-3% standalone is perfect, beats all the rest.)
