It will definitely be in the RDA. A smaller, narrower, reduced top cap/chamber with moderate airflow will produce more flavor due to the reflective heat and more vapor to fresh air saturation than a large, very loose chamber/top cap atty will. Examples would be look at the older IGO W version 1, Helios, Atomic, Derringer, Bambino, also as Pushbutton posted the Chalice, Cyclone, even the old A7, maybe even a Paradigm all share this aspect over say a Patriot, Cerebus, Velocity, Mutation X, Doge, etc. Next will be in your coil, a smaller diameter coil with higher gauge wire, even a twisted pair single coil will pump out flavor like not body's business all day long even in the 1.0 to 1.5ohm range with 28awg twisted on a 2mm or 2.5mm diameter. After all that then it is in the watts, about 25 to 35watts I use personally on a single coil Derringer with a 1.2ohm single twisted 28awg on a 2.5mm, flavor for ever on that bad boy all day =).
Takes practice and experimenting, but definitely look at a reduced chamber RDA for the start, maybe a Paradigm, Vector, even a Tugboat RDA will get up there in flavor, Derringer and Bambino also.
