The piece of SS mesh works as Q mentioned but I was referring to a vape band that I have seen on some sub tanks ... think of a rubber band with various size holes in it or in your case maybe just one small. You can position this small hole right on the hole on the device, thus reducing it. Oh I have one, here is a pic. ..What's an air ban?
Edit - looks like Q answered.
I hope air isn't an issue for me (too much). And it doesn't effect flavor and harshness when/if I cut it off with as mesh or something... That was how I felt with the Hurricane when I turned air way down. Too harsh and became over saturated..
Also - I think the KF4 and KM3 have a very nice draw (and also very quiet, since the restriction occurs inside, if that makes sense).
Q - I hope you are wrong and there is still air adjustment inside the pin also/in addition...?
