I've been a long-time Arctic user and enjoyer. Today I received a pack of 0.2 ohm Arctic coils from fasttech, and noticed these are BTDC II coils. I ruined my first 0.2 coil by turning the wattage up too high, so buying these was my second attempt. But I noticed they are different than the older 0.2 coils, hence the II in the name I suppose. I have no older 0.2 coil to compare to, but these seem to have a thinner "screen" on the outside of the coil, allowing faster wicking, as well as a larger diameter coil, for more airflow. Anyone else have these and know for sure? So far, coil I installed tonight is indeed wicking faster, and is running at 79 watts after priming...?
