Hey y'all, getting a whole new vaping set up. I'm pretty set on a red sigelei 150 watt, but now this discussion, it'll be about rda's. I currently have a few, but another won't hurt. I'm tied between the Derringer or the Troll RDA (leaning towards the Troll, because I'm a meme fan) both clones and in a black finish. So from the two, what would you suggest? Thanks, y'all!
