higher PG is better for stealth, also some flavors seem to work better. I have found that a 100% PG 'Red Hot Cinnamon' from another vendor works great (and since PG aggravates my throat, the cinn oil soothes it at the same time) I work around kids so the stealth vaping comes in VERY handy on long photo shoots.
exhaling through your nose also helps.
I would love to see FSUSA do a couple of 'Stealth Juices' so i can dump the uber sweet 'Red Hot' stuff... for me the ideal stealth vape would have little to no vapor on the inhale (vapor escaping your mouth upon inhale is a dead give away), and deffenetly something to counter the effects of a high PG juice (dry mouth means more watter, more water means I have to 'go' more often, not good when you have to work 6 hours without a break.
