Or, another perspective . . .
At the end of this post, I'm going to say, "you should try switching to unflavored nic salts @ a much higher percentage of nicotine and don't inhale. rather, mouth draw and then gently out the nose." This will satisfy you completely (including "throat hit" equivalent), eliminate involvement of lungs, drastically reduce any irritation of the throat, and eliminate flavorings as a factor.
I started out and stayed at ~35mg MTL.
Years later I switched to DL, and enjoyed 15mg Lung hits at ~80-90 Watts as my ADV.
Then, one day, for no real good reason, I experimented with nic salts (@~45mg) and MTL (about 6? years into vaping). I quickly and comfortably transitioned fully to that.
Then I went to "mouth to nose" (no lung . . .. the out the nose thing is very satisfying), and then eliminated all flavors from my deal.
When I was comfortable (mindless ADV, "normal") with unflavored, mouth-to-nose vaping, I dropped down to 25mg salts (only partly salted).
And when I got back down to 20mg, I switched back to freebase.
Soon I'll be vaping mouth-to-nose @ 15mg, unflavored, freebase. And that's what I was vaping DL @80W and flavored, just a year or so ago (or less?).
Here's the point, tho: when I was doing the salts at about 35mg (first step down), I mixed up some unflavored freebase @35mg, and it was harsh to me! Very harsh on my mouth and throat. Simply could not vape it type harsh (and that's what I was vaping for years when I first started).
So, the salts will alleviate much of the "wire-brush" effect on your breathing passages (mouth, throat, etc).
Higher levels of nic (as salts) will allow you to feel satisfied as you switch to MTL and then to MTNose.
Then your lungs won't be involved at all, you'll be getting your nic, and you can drop back down in percentage (and then to freebase) as/after you become fully accustomed to your new vape style.
(I understand that nic salts may or may not be evil; but, as a short-term transitional aid, how much harm can it do?)
(also, I may come across as smug/certain/knowitall in this post; but, it's just an accidental consequence of trying to limit myself to as few words as possible. please to add generously: "IMHO" and "in my personal experience", and "who am I to tell you what to do")
So, "you should try switching to unflavored nic salts @ a much higher percentage of nicotine and don't inhale."
ADDIT: forgot to mention, this MTNose vape is at about 15W.
