I would say butterscotch is my ADV. cause if I run out for errand or whatever that's the juice that's with me. It's the one I take to bed with me.. Lol well to the night standOh believe me, I fully understand you point of view, I am also a customer of theirs, in fact I rarely get juice from any other vendor as most of what I got from MBV suits my taste and I haven't had a need to do a lot of searching for other juices.
I have yet to find something I could use as an ADV, but I do understand that if it is OOS that is a pain in the ... and frustrating, but by the same token I understand the circumstances that arouse with the issues they were having. I guess this is one advantage of not having a ADV at this point and I know I would be greatly disappointed if there were some juices that I love that were OOS, but also understand that sometimes things are out of the control and have to be dealt with as best they can. I wish I could find an ADV as then I wouldn't have to keep getting so many different juices, oh hell who am I kidding, even if I had an ADV, i'd still get different ones thanks to all the gals and guys here!
I had however been vaping a juice I was originally not all that thrilled with but after a month I have vaped it for 3 days and have more on order, but I still rotate about 4 flavors a day.
But I have 5 others by my chair that I ditch back and forth during the day but I always go through at least 5-6mls of butterscotch a day.

I'll just vape all pyrex and not worry....easy-peasy!
