slightly off- topic, but have you used your AGI as a tank very much? if you fix the crappy spring connection in the center tube, it vapes equally as well as the dripper IMHO. I measured the resistance of the post with the original spring and it was nearly 1.2ohm loss. I used a small brass pin that fit tightly inside the spring, cut to fit and no loss of resistance through the center post. on my next tank fill I will take a pic or two. super easy fix for great results!!
Never used it as a tank. I bought it solely as a dripper until I knew I could replace the spring inside the tank shaft. If you try to run a sub ohm setup on it, the spring just turns black and collapses. I actually had a guy cut some brass tube for me since I don't really have anything to make a clean cut with. The tubes are being sent to me right now. Thanks for letting me know.
