The B2K would very likely fit your vape style nicely. It's one of the best single coil rdas out there imo. Just a bit hard to find anymore.
Next one I would look at, which has very similar amount of airflow a the elder dragon, is the KRMA (the clone at fasttech are super cheap and work very well). I build both with the same .17-.19 ohm coil and they both run great in that range. The KRMA is great for squonks since it is so hard to get to leak.
Lastly, the reload s is another good contender. It is similar to the recurve, but the reload just preforms better for me.
