I just got my Tornado this past thurs; my first e-cig; and maybe its ignorance, but, I've noticed that compared to an analog, it seems hard to drag off of it. I've changed carts, done the Fluval cart mod, tried different atty's, tried different brand e-juice, the list goes on. Am I just not used to it, or is there something I'm missing. The Tornado makes tons of vapor and tastes great but it feels like I'm trying too hard to get a good drag. Any ideas.
