I didn't come up with this recipe, but I've been looking for it/something like it. It's pretty close to Dr. Crimmy's Beetle juice (pretty sure that was the originators intention, although it might have been him that submitted it in the first place in 2012)
3% Mango 5% Pineapple 5% Raspberry 6% Strawberry I use TFA and It's my current ADV. At 50/50 the throat hit is perfect. Not harsh at all, but present.
I made all variations of this when working on a Betelgeuse by Nicoticket clone. I don't know if you ever had Nicoticket's version, or how it compares to Dr. Crimmy's version but it takes this base recipe to a completely new level. I urge you to try this clone, you will not be disappointed. Hell, PM me your address and I will drop you a bottle.
