I've struggled with finding juices I can taste as well. I started vaping 2/2015 and still trying things out. I vape 3mg. Ones I've found to be bold are: MBYC by Sicboy (Primary Flavors: Praline, Vanilla Ice Cream, Custard).
Lushington by Stash (peaches & cream-hands down best real fruit peach I've ever tasted w/ light but rich cream). Dark Star by Stash (bready custard, chocolate, caramel)
Hades by Cyclops Vapor (bold coffee, mocha and nut notes).
Sweet Complexity by Vape Wild (brown sugar, banana, cake, nut, cinnamon-sweet and complex no boost needed) and On Cloud Custard by Vape Wild (I get this with a boost, 50/50 and it's still one of my fav cheap custards).
Pineapple Cream (sweetened) by Ahlusion (pineapple w/ soft-serve ice cream), Lemon Vanilla Cake from Ahlusion (real lemon (not candy) w/ light white cake/cream) Tiramisu (Xpress line-bold coffee, cream, cake). Ahlusion has a ton of fruit flavors that many people love but I found most of my samples too light or I just didn't care for the flavor. The bolder AHL ones I've tried were: Strawberry Sunset (peach, strawberry, nectarine), Peaches & Cream (very peach forward), Caramel Apple (Xpress line-apple forward), Canyon Sun (orange and cranberry very bold) and Lemon Cream. I usually get AHL in 50/50 or 70/30 blends. Hope this helps.
