I had thought they were discontinued as well, but I just got my most recent ones ordered on 5/11, so I don't know if they brought them back or if that was the last of them.
I also figured out the other two flavors I forgot, which were Honey Flue Nut and 555 Exotic. One thing I will say about the 555 Exotic is that it is in my opinion very aromatic and strong in flavor. You can't really hide vaping that one lol. I actually love the scent of it myself, even though I don't like tobacco flavors.
They said a while back that there would be one final run of RY4 and eJoker, and then it never came. After a while it showed up randomly, so I don't know if it's back for good or if that was the final run. Let's keep our fingers crossed, because BWB RY4 is some of the best juice out there imho! One could probably find the Backwoods vendor threads to get an answer, but I'm not patient enough to sort through page after page of effusive praise that you find in those threads. Even when they come out with a bad juice, people rave about it.
Yeah, I'm quite fond of the 555 Exotic myself, and I can't believe I forgot to mention Honey Flue! I haven't tried the Honey Flue Nut, but I'm sure that's a keeper as well. For me, the most aromatic juices have to be the Halo juices -- there's no stealth vaping those! Sometimes it's a good thing, like with the Belgian Cocoa, but Bella Valente for example, tastes good, but smells to me like a wet dog!
