Mrs T uses a mostly vg mix. Try a vg liquid anywhere and see if the pg is what is offending your tastebuds.
I know the 'funny tang' of which you speak. At least there's something in all the juices I've ordered (except Ms T's Bakery) that is really off-putting to me. Because of your comment I'm thinking I ought to try something from ivape.
Regarding Pink Spot, I expected to really like their juice (after watching/reading some really positive reviews), so I ordered Dutch Apple Pie, Blueberry Cobbler, Washington Red Apple, Pink Spot, Banana Cream, and Butterscotch; they tossed in a free sample of Tahiti Breeze. Sad to say (because I really do hope their business succeeds!), I didn't care for any of it. For me, their juice contains that "funny tang." I've decided to let my vials sit for a few months and try them again -- hoping for my taste preferences to change or for whatever the weird twist is to steep out. While I hesitate to add a negative review to the thread, I feel it's right to let people who are noticing in other juices that "funny tang" thing (which I think of as some sort of weird, chemical, funky twist) know that they might find the same thing in Pink Spot juices.
I suppose the lessons I've learned here are these: 1) don't trust your taste buds to love what others love, and 2) don't go overboard on your order.
To sum it up, Pink Spot juices aren't a hit for me, but that doesn't mean they won't be for you.
Oops... "funny wang" not "funny tang" -- my bad! (edit note)
