One 3.2mm airflow (at largest) leads to it not even mattering how big they make those outside slots, 3.2mm's of airflow is the best you're gonna get. I find that to PERSONALLY, keyword, to be very limiting. ALTHOUGH, if you like TIGHT lung inhales or mouth to lung inhales, this tank will probably be king motherfucker as SvoeMesto is a baller at designing his shit and making sure it's made to exact specification. Cannot say the same for the $15 Tobeco clones most people use then proceed to bitch about how bad their Kayfun is.
I wouldn't get TOO excited seeing those slots, as having only one 3.2mm airflow (at largest) for intake is going to severely limit the amount of air coming in. So, expect a TIGHT lung inhale at best, but a relaxing MtL inhale if that's your thing.
Like I said, 40W and below, for those 'tootle' puffers, this RTA will probably be king. I don't know if it can beat the Hurricane or the Pico, but I'm betting it will.
EDIT:
I just closed my Boreas down like 92% of the way to simulate a 3mmish draw. I hit it at 162W with success but and OVERWHELMING throat hit that had me coughing like I just smoked a whole pack of unfiltered 1920's Pall Malls at once. So evidently, to some certain badass who likes high wattage and low air, this in theory could bust out the high wattage. Results may vary.
