I'm trying to figure out why you would want to vape at 200 watts. I mean, your mod may produce 200 watts, but 30 watts per coil (provided your airflow is completely unrestricted) is far above what's needed to produce thick clouds of vapor.
The TVF4 breaks 100watts easy on factory coils. The problem is you'll spend more time filling the tank then vaping it. Also get some oven mitts because that thing will get hot quick.
