I'm very very interested in this new gemini. Specifically, the atomizer and the PCC. I have an AWFUL lot of 510 "stuff" and even got some 306 atty's so I could dip with my existing 510 batts. Also picked up some adaptors so I can use a 808 cartomizer with my 510 batts as well. I never had a whole lot of problems with the 510 PCC, per se, but I'm exceedingly interested in what you have to offer. 3 carts for the existing PCC is pretty darn lame, but I just carried a bottle of juice around with me to top off carts with and I was in good shape. It would be nice to be able to carry enough filled carts to not have to do that...
I already have a pretty impressive collection of PV's (for somebody who's only been vaping since november or so), but I'll probably buy a gemini kit when they're available. I am curious about the atty design, though. Is the atty hidden "down the rabbit hole" like the existing 510, or will it be more accessible like the 306 / 401 / 602 models? I've become quite a big fan of dipping while at home, and that would be nice to have as an option.
Also, if you guys are looking for another PV to give the "revolver treatment" to, consider smoore's 602. It is, by a large margin, my favorite PV right now. The throat hit and amounts of vapor ROCK. Only real problems with them are cart capacity (not that big of a deal since I usually dip it) and THERE IS NO PCC.
Anyways, enough rambling. Keep us posted on availability of the gemini, and have a happy new year!
