I just re-checked my RBA... I stand corrected the airflow IS the same as the OCC. It was the big 25mm RBAs that had the reduced air. My Bad
I still can't imagine my thick juice is going to feed through those tiny holes fast enough to keep up with my chaining though.
What are your coil stats? I might give it a try before my next OCC rewick just for grins. (wire gauge : mandrel diameter: wrap count) I am interested in trying some of the twisted 28 I have lying around from my dripper days. Twisted does give more surface area but also requires more juice flow to keep up.
