I been messing with my AGA-T2 and yes I must say the flavor is way different than the smoketech tanks I was using. The flavors seem a little less strong. I can vape flavors I have not been able to vape in anything else. Mainly because they were overpowering and really funky tasting in a carto. On the AGA-T2 they are amazing perfect amount of flavor with out being over powering. I'm not running monster power or anything so cant speak for high watts or voltage. I'm vaping it @ 2.0ohm hitting it with 3.6v I had drilled out the air hole as it did seem tight, but I found not that opening it up to 1/16" creates an air flow that can keep your coil a little cool. I have covered it back up about half way with a little piece of clear tape and the vape is much thicker. I suggest you not drill out the air hole, or if you do find the next size down from 1/16".
