Thanks for all the great feedback everyone!
Kiwivap,
Thank you for the detailed info on the RY4. I was really looking forward to it because RY4 is my favorite liquid flavor to date and I like trying them from different vendors, trying to find my ADV. I am super disappointed to hear that MBV RY4 has anise flavor notes ... like you said, that isn't like any I've tasted prior. I really, really dislike anise in anything ... I can't stand the smell or taste.
So, although I will give it a try ... It's likely to go to waste in my home.
