How to choose an RDA to play smoke? This is not a difficult question to answer, because there are already many RDAs that optimize the ability to create the strongest smoke possible.
When a manufacturer deploys their R&D team, they are already aiming for a vapor RDA or a flavor RDA. And the chamber size, airflow, and build deck size will determine which category the RDA falls into.
Standards
Body: When looking at the chamber of the RDA, if it is large and far from the build base, it is a vaping RDA. The reason is because the chamber will provide a large amount of air along with the vapor. If the build chamber size is small and close to the base, it will give you a better e-liquid flavor. However, if the RDA has a small but airy build chamber (wide air holes), you can still vape.
Airflow: One of the most important parts of an RDA for vaping is the airflow. Most RDAs today have adjustable airflow, but sometimes even those don’t provide enough airflow to produce the strongest vapor.
A vapor RDA will have a wide airflow system and a wide drip tip. The more air you can get in, the bigger your vapor cloud will be. A flavor RDA will have a more closed airflow system, because less air will make the flavor stronger.
Build Base Size: Although build size is not important for RDA design, a large enough build base will help users install large and complex smoke coils. The same goes for flavor RDAs, the base does not need to be too large, but a large base is still a reasonable choice because some flavor coils are quite large and complex.
Conclude
Ultimately, the choice is all about personal preference. There are many flavor RDAs that can produce thick vapor and flavor RDAs that produce extremely good vapor, so you just need to choose an RDA that meets all three criteria above and build a pair of coils specifically for vapor.
