Review of RY4 Double Flavor-TFA:

I'll preface this by saying tobacco flavors aren't my favorite.

That being said, this flavor is pretty good. There's a lot of potential in the sweet, complex flavor of RY4 Double. My favorite ADV for the past year and a half has a bit of RY4 hiding in it, so I decided to try to clone it. On my first two attempts, I realized how powerful the RY4 Double is. At 5% (as part of a multi flavor mix), it ruled over the juice with extreme prejudice and an iron fist. At 3% (in that same juice), it became much better. If you're into RY4, this is a great place to start. If you aren't super into it, but think it adds well to certain flavors, beware it's potency.
