Try the opposite of the typical analog smoking technique (quick 1-2 second drags).
Instead take a slow 5-second drag into your mouth/throat, without swallowing the vapor and exhale it after 1 second. Try it again except take the drag into the lungs directly this time and you'll have less vapor. Try a third time with into the throat and THEN into the lungs and compare to the first two methods. Your vapor will vary!
Juices in ascending order of vapor production are Premium, Wow, and VG.
If you are using prefilleds, coolcarts have premium, Wowcarts have wow, and VG wowcarts have VG.
