The lemon and custard were cool (I used 0.5 sour), but I thought the fruit profile was weak. Would recommend adding more flavors such as (Blueberry, Wild (TPA), Blue Raspberry (FW) and Boysenberry (Flavorah)).
Thanks for the input. Not sure on the Greek yogurt Fredrick, I think it would change the flavor to something completely different. Try it out and let me know how it goes.
