I didnt start with analogs so i'm not huge into the throat hit stuff
VG (Vegetable Glycerin) liquids have less throat hit than PG (Propylene Glycol), plus VG produces more voluminous smoke plumes
The higher the nic content the more harsh the throat hit will be, stick to 8-12% if you want nic but no TH
Also let your vaporizer have time to cool between pulls, your TH will be lessened if you get a cooler draw
