Just depends on the day for me. I'm 5 weeks off analogs and somedays i wake up and can't stand the TH, so i'll french inhale or inhale just enough to get my buzz and then exhale through the nose. Other days, I'm fiending for my fix

and nothing but a good deep draw will do.
My question is this: how long do you generally pull on your PV? The reason I ask is in most videos people tend to draw for 3-5 seconds (some longer) and most people who smoke cigarettes look at me crazy when i'm taking my 6-10 second draw off my eGo.
