The Zeus is alot more airy then the Merlin. I usually prefer a somewhat restricted DTL . Closing down the airflow on the Zeus produces great flavor and turbulence is never an issue with mine. Somehow I got lucky with my Merlin as it has never leaked/seeped a drop of eliquid but is a little too restrictive even with the largest airflow adapter.I don't know if I would condemn all bottom airflow and/or press fit atties as my Subtanks and Toptanks never leak either.

I think you will really like the Zeus Dub.
