Hi, Bunny.
Unfortunately, I don't think I can adequately answer that question. The two that I have now are described as "nutty, caramel tobacco flavor", and although my person description wouldn't quite match up to theirs, it's decent, although mild in taste. The other is simply a mango flavor, again on the mild side, but okay. Although the owner couldn't provide PG/VG ratios, it was stated that they were "mostly" PG, if that makes any difference.
I went down to the same shop, taste tested other flavors, and didn't get a thing. Also hit the local AltSmoke and tried a number of juices there -- the only one that I semi-liked was the NicQuid Blueberry (or Blueberry Tart).
Based on that, I think I'm more preferential to fruit flavors.
On an aside, after trying a few juices at the local shops, well, I don't think I'm going to do that again. My fingers were getting all sticky from what I can only imagine is old juice on the outside of the juice tester clearomizers there. Bleh - that alone could have had a negative effect on my dislike of many of the juices. I know I'm a slight germaphobe, but it wasn't the best of experiences. I like to keep things clean, wiping down my own clearomizers and batteries after a refill and when putting them to bed at night. ;p
Thank you!
if you let us know what your preferences are maybe we can give you some good leads to better juices

are you into tobaccos, fruits, creamies, etc???
