I understand you're wanting to gain some leads with this post, and that is cool. But as you fully understand that taste is subjective, and considering you're going to see mention of the 3 juices you named about a million times, you might as well, as your wallet permits over the next few weeks or months, try all 3. You know you're gonna do so sooner or later... especially the Bobas and Bounty Hunter. I've not tried many RY4s, but I understand they do vary signifigantly. So perhaps not limiting to just RY4s is the way to go. Go with the most popular unique juices that are or hint at the tobaccos.
BWB 555 exotic
Vermillion River Kentucky premium
Cooper Creek House blend
Rawr Poison
Halo Torque
Vaperite RY4
AV Gorilla Juice
AV Raf-a-licious
Dekang Tab & RY4
BWB Malty Toffee
God, there's so many. What have I left out guys? Especially in the RY4 catagory, since that's the focus.
