I copied this from ECF from
@Eskie
So after some more playing around, lowered the coil just bit more than I'm used to getting closer to the air holes, and nicely wicking cotton, and the flavor on this is really coming out better. About 2/3 open on the bottom air, closed on the top. I'm glad I didn't make a snap decision on it, it's better than I thought at the start. If the vape isn't right on, play with the coil height, which seems to matter, and the airflow. Once dialed in, even this single deck is performing nicely. I take back anything mean I said about it (although it does look flat out stupid with a 510 DT on, see below)
Hope this helps
