Try the Blend 4, it is the best cigarette flavor I have found and very substaintial. I thought the bobas was a little sweet but I really like adding it to other flavors like their C&D. The Blend 4 is my all day vape. I also tried the Gamel and the Flue Cured. I like the Gamel a lot also as it taste like the C&D but with a little more bite to it. The C&D is perfect for mellowing out any too harsh flavor and just adds smoothness. My least favorite is the flu cured as it just taste kind of flat to me. I keep the bobas, blend 4, C&D, and Gamel in stock as I really like all of them. With all the juices I have tried if I could only pick one it would be the Blend 4. I shake mine up before pouring and have noticed bubbles also. I don't know why this is either and thought it kind of strange. Maybe it is because he doesn't add a lot of water to it. His juices are the best. I plan on trying the caramel, irish creme, and toffee ones next as I like to add a couple of drops to sweeten flavor sometimes.
