Well, I find more flavor from 302s - with "good" airflow. Airflow can get complex because beyond the atty itself there is the adapter and the native connectors. With each component, there are variations from different manufacturers. For example, if we take the same atty and adapter and put it on different devices (each has a different connector and each connector has different airflow), we get slightly different experiences. Similarly, same attys with same device and change the adapters = different experiences, etc.It sounds like you are saying that I would probably find a little better performance in the 302 but for a very short duration.
So far, from my experiments, it seems the "801" atty may be the most durable (long-lived), 4072 the most fragile (although good flavor) and the 302 and BE112 seem to come in fairly similar in durability.
But, this can all be functions of vaping patterns as well. For example, the 302 has the biggest airholes. This design could be intentional and if we use a less airy adapter (and/or even slightly tighten further with the flat-head adjustment), we could be restricting airflow beyond what the atty might be designed for. IF (BIG IF) this has any validity, I could conceive of the possibility that we might be over-heating the atty which might contribute to the ohms drop. Another possible factor could be vaping style. I tend to multi-hit (rolling like a pipe smoker). This could possibly be impacting the coil resistance (over time) compared to taking one draw and then letting the coil cool - even for 20 or 30 seconds. All speculative theory. But, I can say that flavor certainly changes (at least for me) with airflow.
