More often than not, your nicotine plays a factor in throat hit. With you using nicotine salts I think you can up the level, until you feel a peppery throat hit. Lots of people tend to not enjoy that peppery feeling. That too can be a sign you are getting too much nicotine.
I use what is called freebased nicotine at 18mg per ml of VG. Like to use max VG juice myself for a few different reasons. I am not exactly a cloud chaser but do enjoy seeing modest clouds at least.
Also for me VG provides a better texture over PG. I lack sense of smell hence lacking a range of sense of taste. I find other ways to get pleasure from vapor.
Many people lower their nicotine ratios once they switch to using RDAs like I do. I have not done that. I vape a bit less juice than a lot of people due to that, as well. On average I might vape approximately 5 ml per day. Seen people that vape 10 to 20 ml per day. Some of them are only vaping 6 or 3 mg per ml nicotine though. It averages out in what I vape to what they vape.
Another tip to consider if using a tank or RDA, try adjusting the air flow control. Some people enjoy a restricted direct lung hit, others like a loose mouth to lung hit. The airflow can often help a person where they desire being. I see you
possibly know the stuff we don't discuss here. Yes, you need to hit or draw on ejuice vapes like that as well. I'm sure if I told you volcanoes rock you'd understand fully.
Vaping is not cigarette smoking, for sure.
