I, basically, did the same thing Medic: Provari (mini) right from the get-go* . I got the Zen atti and use the Kanger II for my walkabout. I have the same problem, it's too big to lug around in my pocket. (I quickly learned that the Zen spilled after spending the night smelling like ejuice...that's when I got the Kanger...I am not a smart man). I'm curious about a 'non-spill', 'pocket friendly' option (money is not an issue).
I'm looking at the Microstick, but am having difficulties finding the right tank to go with it. I'm going to post to the main forum, as well.
*I got an eGo from MadVapes and used for a few weeks before buying the Provari. btw, Provari rocks....it's an incredible piece. I just feel that it's best left for home.
PS - I can't wear a lanyard or anything, as I'm a businessman; this is also why the Provari is difficult, my slacks easily accomodate the Provari sitting sideways in the pocket (unlike blue jeans)
