Increasing Flavor and Throat Hit in an RDA
If you're looking for more flavor and a better throat hit from your device, there are several things you can do. The size of your coil, type of material used for your wick, the distance your coil is from your airflow, the amount of airflow, and the VG/PG ratio all affect the taste and feel of your hit.
The most important factor in increasing flavor is the surface area of the coil. A larger surface area means you'll be burning more juice and flavoring. The type of wire used is also a factor. Using twisted or Clapton coils allows juice to fill the nooks and bring out more flavor. How the coil is wicked is another factor. You can't have too tight of a coil or the juice won't be able to travel up to the coil fast enough and will result in more dry hits. If the coil is too loose, you'll end up with spots that are hotter on your coil and have dry hits as well. Airflow is another factor in flavor.
Basically, the less airflow there is, the more flavor you get. A fully open or very airy RDA will result in less flavor. An RDA with the airflow openings right next to the coils will help with giving more flavor due to the air being able to flow around the whole coil.
The key element to getting a good throat hit is heat. Essentially, the hotter the coil, the better the throat hit. If you're using a mechanical mod the best way to get hotter coils is to build a lower ohm coil (be careful). Look for a battery from a brand you trust that has an amp limit of at least 30. With an electric mod you want to increase the wattage/voltage. For the wick, you want to use cotton or rayon as they burn hotter than silica. As for the coils, thinner wire and shorter coils will be hotter at the expense of cloud volume. One of the tricky aspects is coil placement. If you want a good throat hit you need to have the coil further away from the airflow intake, but that may come at the cost of flavor. You're going to have to do a little experimenting to find the right distance for the right balance of flavor to throat hit. The amount of PG in the juice will influence throat feel as well. The higher the PG, the more feel it will have.
There’s no one answer to the perfect build. The type of e-juice you use, the RDA you're using, and personal preference are going to determine how you build your coil. Through experimentation and adjustments, you will be able to find the right balance for you.
