The Profile also has AFC's that can be stopped down to just one very, very small hole, so I would think is as restricted MTL as you can get from any atty - yet they can also be open air for us big air DL vapers.
That’s not how restricted MTL works. It’s not just a matter of cranking down airflow. Wide open chambers are the worst for restricted MTL, because you’re sucking a tiny bit of air through a large chamber, so it won’t hit the coil at decent velocity. Not to mention it’s side airflow, so some won’t even hit the coil directly. There’s a good reason the best MTL
rda’s and RTA’s have bottom airflow, reduced chamber size and inserts for the bore under the coil.
