I mixed my 80 20 juice with a 20 80 ry4 and it works great. Tastes great too but I'm looking for something that I don't have to mix, so I'm interested in 50/50 juices. I just recently tried the VG heavy juice in one of my clearos and it reacts badly if its set on its side for even a minute. I really like madvapes nutty caramel but I'm gonna get a dozen FSUSA samplers because 50 50 works better in my clearos and I'm bound to find one I really like.
