Throat hit means different things to different people. It can also be adjusted... using the same juice.
For me; and I only speak for myself. I don't need to nearly gag on the 'vapor' / smoke. IE: it doesn't need to be so thick or punchy that I find it discomforting. But I can't have it just be like air. I have also found that thick vapor feeling the vapor go down is good enough for me, rather than - harsh throat hit from high nic.
For those wanting to drop nic, but still feel the vapor the whole way down. Menthol. Find the coolest menthol you can, not the peppermint or anything that produces a 'hot' vape and you'll be able to feel it - without getting the super harsh high nic type hits you get trying to seek the sensation with higher nic juices. But menthol and nic work well together. The menthol is a good cool numbing agent. Give you that deep draw you can really feel, and taking away some of the discomfort of doing so.
Another way is air. Air plays an important role in my flavor junky fix that has pretty much consumed my vaping habits. More air, less throat hit. (And flavor.) I now use high output devices, and low nic juices. And adjust the airflow until I get the balance just right for me at that moment. If I put 18mg MASS menthol that I would run in a protank or DCT in say the aqua... I would be on the floor. It's just a quantity thing. The aqua vaporizes twice as much juice. If you cut the airflow way down to get an even more dense hit. I could gag most people with a 6mg juice. You would swear you were sucking on the flavoring bottle.
I meter out throat hit this way now. By density of the vapor and concentration via airflow. No need for high nic, or harsh juices.
There are many ways to get where you are going. Find what "you" like, and that's all that matters. But if harsh hits, and higher nic juices aren't your thing, - but you still want that feeling. Equipment can also play a role in getting there.
