Opus Elixer's Rex (Kiwi and Strawberry) clone?

[QuestForVapology]

One of the most popular juices in NYC. It's beautiful. It's also really strong.

Anybody has any idea how to clone it?

I was thinking it's gotta be some mixture of
TFA Double Kiwi
TFA Strawberry Ripe
TFA Strawberry
TFA Gummy Candy

and a ton of sweetner, which I'm not too familiar on which to use.
