@WonderDude32 - I've had excellent results with TFA Greek Yogurt, but it's the only one I've tried. I picked up a bottle of FA Yogurt last week, but my tester is still on the steeping shelf and I haven't tasted it yet (though it smells like the right stuff).
Here's what I added to the Greek @5%:
+4% TFA Key Lime = Excellent
+3% INW Peach = Excellent
+3% INW Cherry = Great
+3% INW Blueberry = Not Bad (2% would have been better)
+3% INW Strawberry = same as the Blueberry experiment
I think INW Shisha Strawberry would have been better, since it's sweeter. In fact, I just laid in a bunch of new INW Shisha Flavors (Bilberry, Lemon, Lime, Orange & Raspberry), so I should probably plan another "Greek Week" experiment soon. Fruity yogurt suits me well in summertime.
