what RDA you are using can greatly effect Flavor, in my experience, Magma is top on flavor, Followed closely by the Plume Veil. the plume is a really good combination of flavor and vapor production because of its airflow. Also, you will get more flavor with more surface area on your coils. in my experience a .5Ω dual coil with 28g in parallel will give much better flavor than not parallel, same number of wraps, ohms, and coil diameter.
In my Magma, i will do dual 28g at .7Ω. In the plume i will do dual 24g at .3Ω. I find in the plume the .3Ω is not too hot of a vape, because of the airflow, but in the magma, anything below .5Ω is way too hot.
As for a suggestion, maybe try a parallel coil, Dual if the positive post can fit four strands.
Edit to add, Wicking material can effect flavor too, i get better flavor from Koh Gen Doh, and Rayon than i ever did with normal organic cotton.
This all just my

, ymmv etc etc
