There's nothing wrong with the Reuleaux DNA200, I love mine. The ability to just swap out the 3 18650 batteries and the watt hours are a big advantage over the built in cells. I also love the ergonomics of it, it's the most comfortable mod to hold I've ever owned. As for the differ csv files the different wire types are available using steam engine. Also you can join many of the Reuleaux DNA200/RX200 facebook groups where you'll find plenty of help getting any files you need.
