I think I have made the same logical progression as most vapers. I started off the a little 450mah ego and a ce4 clearo and thought to myself "THIS IS ALL ANYONE NEEDS!". Then I got an evod tank, a protank1,2,3 and thought wow who needs more? Then I got a vamo and another array of protanks and figured welp this is it, the pinnacle of all vaping experiences. Before I knew it I was rocking a provari and kayfuns, taifuns and thought well ill be this is all anyone in their right mind could ever want. After a bit I was holding my ipv2 with a dual coil tugboat and im certain this is all anyone would ever need. Now for my problem........I still like to take my provari on the go and im finding my kayfuns and taifuns to be completely unsatisfying. The draw is tight and the vapor production is low. What is the current hotness in rebuild able tanks that I can stick a 1.5-2ohm microcoil in and get some airy draw and lots of vapor for use with my provari?
