When the rotating AF plug in the Orbit is fully open, it's a 4.5mm af so the airiest of any BB RBAs I've got. Airier than the VapeSnail which has a maximum 3.5mm af and the Qbix which goes up to 4mm diameter.I feel the Orbit was designed more for mtl vaping.
I agree about the Orbit's small juice wells - that's the limitation with a wide deck on a square angle. I guess it was a trade-off between smaller deck or smaller juice wells, but somehow it keeps up with a 3mm ID coil and no thinning. Never had a dry hit or any problems with wicking mine.
The deck of the VapeSnail is much roomier because of the diagonal setup. Better design but I wish it had af as smooth as the Orbit.
That new Voltrove RBA looks like it's designed for lots of air. Not sure of the specs under the coil but it looks cloudy in reviews.
Good point.Last but not least the deck having four parts to it instead of two. I mean doesn't that reduce conductivity?
