Now that I have a Black Boreas I have to say it. Boreas > Aromamizer Supreme. Yeah, I get a little bit better flavor off my Supreme, but that's all I get that's better. I can actually fit 10 wrap 3.2mm 28x2 with 32ga fused claptons in the Boreas where-as I can only fit 9 wrap 3mm fused claptons in the Supreme. The Boreas with its bigger build deck and higher amount of airflow lets me literally cap my .6 fused clapton build out at 9V at 142W. That's the maximum voltage power output of the DNA200, so that's just amazing. If I had like a .3 ohm build in here I have no doubt it could handle a full 200W with no issues. The Boreas also doesn't need knurling, I find the metal on the Boreas to just be very naturally easy to grip, there's no slippery/sliding issues when I go to take any part off of the tank. So the Supreme gives better flavor, but the Boreas is cheaper, sexier, holds more juice, has a bigger build deck, and just throws down some baller clouds with its allowance for huge builds. If the JFC and airflow on the Boreas were separate, I'd probably retire my Supreme's. I love the Boreas, and it's beaten the Aromamizer Supreme for me for sure.
I'm not sure what the overall diameter of each airflow hole on the Boreas is, or the chimney, but Roxy, a suggestion. If you didn't already do it on the current Boreas, if you ever design a V2 make the chimney diameter the same measurement as the combined diameter of all the airflow holes added together. That way the flavor output will be as good as it can be, and separate the juice flow control from the airflow. If you can do that, and make the build deck a LITTLE bit bigger, you will literally have designed the perfect tank in my eyes. You came pretty damned close with the Boreas as-is though.
