If you're vaping around the 50-60 watt area, you don't really need a more powerful mod. The Subox will do that. If you're getting dry hits, it's the tank, not the mod. Obviously, the mod can make the power or you wouldn't be getting dry hits. However, if you just want a new mod, I can recommend the Wismec Reuleaux RX200. I have 2 of them and love them. I am also partial to the Smok Koopor Plus, and anything by Sigelei.
