The Velocity RDA is a excellent atty. Infinite airflow options, best build deck I have seen to date, quietest draw I have ever heard (unless you only have it open a hair). It also traps leads against the wall of the post hole, as opposed to nearly every other post hole atty out there that drives the screw through the lead, which means it is far less likely to clip them. It only downside is there is no single coil option, but other than single coil, it can do everything well.
