I have had the Mahalo, which I really liked though not as much as the Snickerdoodle. It's a great fruit flavor that isn't overly heavy on the berry, more of a rounded out red tropical fruit, with a hint of melon- or maybe guava? I'm just glad it didn't have pineapple. Love tropical fruit, hate pineapple.
The only miss for me was the Mad Matador. I didn't hate the flavor, but the vapor just kept going straight up my nose! I don't know if it was because it was the first Aroma vs. Red Tail that I picked up from Jerry, or what. I will admit I don't drink Red Bull, I've only actually tried it once. I remember it being overly sweet and kind of citrusy. The Mad Matador isn't overly sweet, which I like, but it was such a weird sensation, like overly carbonated pop. I've been mixing it with other liquids, and it makes a good refreshing base. I'm still making my way
through the Aroma WTA flavors. Wish the Cappuccino came with the WTA.
