i can't say for sure because until I see a picture I'm just speculating based on your description, but that being said, you sound like you're on the right track in terms of what could be the problem. Especially because of your description of weak vapor and really harsh throat hit, my first step in improving it's performance would be to make sure the airflow isn't misaligned and that means it has to be in the right place on a horizontal plane and a vertical one. Often people overlook the height of the coils and just make sure that it's in front of the airflow, but if it's not raised up high enough the airflow won't be hitting the coil and will definitely produce less that satisfying vapor as well as flavor. Hope that helps. Keep us posted on if you resolved the issues or if you run into any other questions. Good luck. Ps it don't want to repeat myself, but a photo or two would really aid us in assisting you. =] stay safe! happy vapingI think your absolutely right. I was at 3mm size wraps. Just not enough power with this AW battery. I tried running this rda at 2 coils last night of 28g, 5 wraps at 3mm running at .6ohms. It had horrible vapor production and was quite harsh. Not burnt, but harsh. It was very heavy on the lungs. Not sure what that means. Maybe my air flow wasn't lined up, or the wicking was bad.
