Quick question.. I saw that it was prudent to order the drip shield, and though all the posts I've seen about it are usually for atty's only, I imagine the theory is still sound for cartomizers, correct? That led me to ponder how a drip shield would work with a tank, since the bottom of the carto is submurged, and only the connector / threads are exposed..? I guess you just take your chances with tanks? and while we're talking tanks.. why hasn't someone machined a flat-sided tank to use with the darwin yet..? Just half a cylinder, with a flat side, so it would close.. someone get on that?!
