Fave Celsius Flavor? Looking for recs.

I'm a Yellow/Tropical Red Bull girly all the way but am trying to aim for a healthier lifestyle. All my coworkers LOVE Celsius, so much so they had the vending machine lady at work switch some of the drinks for them.

I have tried the Sparkling Orange but I'm not so much an orange flavor person, Tropical Vibe but it was waaaay too sweet, and Mango Passionfruit which I can't remember if I liked or not since it was a long time ago.

What's your faves that aren't too sweet and could possibly be similar to the yellow redbull?
