the reuleaux DNA works unreal with my heracles and the 0.2 ohm coil so I imagine the RX200 will as well. Also IPV D3 will be coming out and my IPV D2 works great with the same tank and coil. Just need to change the single 18650 out every few hours if you are chain vaping at 60 watts which is how I toot the thing. The reuleaux will last me 2 nights almost chain vaping at 60 watts with Sony VTC4 batteries. Im dying to get the Heracles Plus now ... I hate rapid innovation!!!!!
