Hello and welcome to ECF, CrazyD. I am far from an expert but I am sure others will stop in and help you with your questions. I started vaping about a year and a half ago. I started with an eGo kit and recently picked up a couple box mods (an itaste VTR and a SMOK XPro65. I have a Nautilus, Nautilus Mini, Kangertech Aerotank V2 and the iclear 30s that came on the VTR). I vap American Tobacco and Black Leaf Tobacco which is the reason for the different tanks. I am sure others will be able to give you better feedback on the choices you are looking for. In the mean time you might want to check out some of the tank specific forums that on here. Of course you won't be able to post in any of the other forums until you have 5 post, so sit back and do some reading while waiting on others. Have a good evening and keep on vaping.
