Funny you bring this up now.
The flavor is way better in the BBB with the RBA than the Prince with it's RBA. However, about an hour ago I took a triangular (Point down) piece of single coil insert and plugged the middle of the Prince RBA deck thus transforming that gaping canyon into a dual airflow deck and it improved the flavor an hundredfold.
Generally, the Smok RBA decks are surprisingly good. Both the BBB and the Prince decks can be a hair tricky to wick. You need enough cotton to fill the gap between the posts, but not stuffed in there either or you could get some dry hits. The ports are pretty small, so unless you use like 2mm coils you'll need to thin the ends a bit, but don't thin them too high because you do need enough to fill that gap between the posts or you'll get some leaking. Also they need to be shorter than you're likely to think at first.
Not bad to wick, but they do like their wicks a certain way. Sounds more complicated than they are.
