fwiw most of the melon flavors (not watermelon though); cantaloupe, honeydew from VZSC, and TFA are good.
Hangsen has the best stand alone fruits in general imo and Inawera, to repeat what another poster said.
I vape a lot of tropical fruit flavors... I always add 1-3% Sweet Cream (TFA is my favorite) to any fruit vape; for me it just completes and rounds out the flavor.
If you want a KILLER fruit ( I mean spot on and strong ) its Hangsen's Pineapple.
