My research turned me on to Highbrow, which happily, is located in my neck of the woods. RY4 is what my son had me sample when i first started vaping. I then began looking for local manufacturers and discovered Highbrow. Being a former 2 PAD smoker, I always order extra flavor, where possible, to compensate for my waning taste buds. Being a former pipe smoker, I can say that their RY4 is the best I have tried. Many flavors (in general) are wimpy. I like extra flavor. The neat thing about Highbrow is that you can customize just about anything. Having said that, I ordered some 50/50 RY4 at 6mg nic. It was awesome. I read a review on their website that basically said that "this is the RY4 that all others should be judged by." I agree. Since leaving the "analog" world, I find that I enjoy tobacco-type flavors much less often, as there are so many other flavors I have gravitated to, like fruits, mocktails, etc.
Highbrow's RY4 is a rich, satisfying, nutty liquid with a hint of chocolate, vanilla and caramel. I love it! Great juices, great company!
