Ok, so I finally got my father to give vaping a shot. He said he did not want a big pv(don't even want to say what he refers my ProVari to), and he didn't want to be carrying around juice. So I ordered him a Pig Cig and ordered some 808 mega lr and also some 808 mega std's(from good ol' IKV, the ONLY place I will get atty's and carto's). I figured these things hold the most juice. So can someone out there give me some insight on how much juice these actually hold, how long before needing a top off(are they as thirsty as 510 gold v2's and Fusions). And lastly hows the flavor and throat hit on both LR and std(he wont care about vapor, but we all know none of Isaacs products lack in that area anyways). Sorry for all the questions, but I just need to feel confident that I made the right decision. My family and I have been trying to get him to quit smoking for years since they found asbestos in his lungs so this is very important. Any insight on these carto's would be greatly appreciated. Thanks...
