I've been vaping for a couple months now, starting with a protank mini on a vision spinner, and have since moved on to primarily using an igo-L with both a tesla and K100. I've been considering adding some carto tanks to my collection because I've been told they are better for using on-the-go. so my question is, do any of you have issues with carto tanks leaking or gurgling the way bcc's tend to? also, any recommendations as far as favorite setups to look in to would be greatly appreciated.
