Hi!
If you don’t want to fuss with wicking and squonking is also important to you, I’d skip the RDTA. Most squonk bottles store a sufficient amount of liquid, and in my opinion, the RDTA’s small capacity tank doesn’t add that much extra. An RDA, however, is the perfect pairing for a squonk system. Wicking tanks can vary for some RDAs, but generally speaking, these are the easiest to build.
Before I/we recommend any Mod+RDA, it would be important to know your preferences. MTL/RDL/DL?
