I've been mainly using side airflow rda's as opposed to bottom airflow. The rda's that I have been using mostly, the velocity v2 and goon 1.5 give off great flavor, depending on the build too obviously. The only rda that I have that is bottom airflow is the tsunami 24 plus. I used to build and wick it wrong but after watching youtube and reading about this rda, I just recently found my niche and I am enjoying this immense flavor that I am not experiencing as much on my other rda's. Now this rda is bottom airflow so I as not sure if it's the rda itself or if in general whether bottom airflow rda's do give off better flavor.
