Finally, I continue to be amazed at how you guys make the pictures of your Provari's look so big. This thing is stealth sized small! I even though the regular was small. The batteries look super small also. However, the unit feels heavy, which is something I like. Is the buying over? I don't know. I know I've got to get into some carto tanks, I also need a ego to 510 adapter and someone suggested I try out some HH357s. I've never dripped, but I'll give it a try sooner or later. So, I know I can look into the cato and tank section of ECF, but do you guys have some suggestions for carto/tank solutions for the Provari? I'd also like to thank you guys, it was your wisdom and experience that led me to take the Provari route and I'm not regretting it one bit!
