Its true. The eGo - T is the natural evolution of those concepts involved in the mods you mention. And it certainly works pretty well. I have also ended up myself using a bottom-feeder box lately as my main unit. But then again, this MJB of yours is by far the sexiest mod I have ever seen; cannot stop thinking about it. I kinda get an erection every time I think of it; heeeeeeee. Nope, just kidding, he. Though, I am a bit kinda obsessed with it. I think it has potential. And personally, I find it could be more satisfactory than both a bottom-fed system and the eGo T.
On a different note now, what do you think about this idea which has been going round my head lately: I have thought that it could work if you had an atty with a retractable bridge (like 2 positions: FLAT, and REGULAR), and a cart which has no filler but liquid only and a kind of silicone plug with a rather huge hole. There is another little hole in the ceramic cup which gets full of liquid at the same time the coil gets plenty and works as a sensor that triggers the atty's bridge motion mechanism. Or this could be manual... Coming back to the cart, though, there is a big hole to the plug, but the liquid will remain inside because there is vaccum created by means of a syringe type of plug up the cart's 'roof'. This also serves as an easy-filling mechanism. So, basically this is the concept and I got this idea as directly inspired by MJB. I would really appreciate it if you were so kind as to give me your feedback on this.
