I don't have a Boreas to try, but all my tanks sit flush (Aromamizer Supreme, Billow V3 +, Billow V2.5, Griffin 25, etc). I consider the Therions 510 one of the better ones I have. That's still no guarantee though.I'm liking the looks of the therion I'm currently using the boreas rta the 510 connection is ridiculously long I think it's 4.8 mm. Is the 510 on the therion adequate to take that or should I find a different tank? I've been looking at the engine top airflow makes me think it will be less likely to leak lol but who knows?

PS I'm not sure if it matters, but the 25mm, 7ml Aromamizer Supreme is my favorite RTA/RDTA.
Cheers,
