I've only had my Dark Horse (clone) for a few days. I didn't have a lot of time to put a build on it when it arrived so I just went with simple 2.4mm 24ga duals. It chucks, even with this simple build. Next build will be some big 22ga duals or some twisted 24. Parallels would rock on this thing too. The post holes are absolutely massive. I'd put a lot of wire on it whatever you do and crank the power up. The
vape on my build is barely warm at 70W. It's thirsty, that's for sure.
edit: it's really easy to build. Not a bad choice for your first rebuildable. I'd be sure to use 24ga or bigger. 22ga would be ideal. 26ga would do if you twist it. Trapping smaller wire in those massive holes would probably be kind of a pain.
