In case anyone is still one the fence between an Arctic Fox or a DNA mod: Evolv just added Session mode to DNA 75C, 100C and 250C. You press the fire button to start autofire and press it again to stop.
In previous versions of the Splinter RBT used Mica to separate the mesh instead of ceramic plate. You can get Mica sheets really cheap on eBay. I haven't found a place to buy the ceramic plates.
