I travel for work and I fly anywhere form 4-10 flights/month. What are your thoughts on the best way to fly with the TFV4 without leaking due to the pressure difference at altitude? In the past with my Atlantis I would just turn the tank upside down and there would be no leaking. With the TFV4 and its top-fill sytem I'm having some trouble working through in my head how it will handle the pressure differential. The four scenarios I can fosee as possible but not conclude which is more likely are:
A.) Upright - Will leak through wick/coil due to higher pressure inside tank than ambient once at altitude.
B.) Upright - Will not leak due to top-fill seal not being perfect seal, allowing pressure inside to acclimate to ambient.
C.) Upside-down - Will leak through top-fill seal due to higher pressure inside tank than ambient once at altitude. May also leak through wick/coil if tank is 100% full.
D.) Upside-down - Will not leak due to sufficient seal at top-fill seal and air-movement through wick/coil allowing pressure to acclimate to ambient. May require juice level to be below wick/coil openings.
I'm partial to A being true, but I'm 50/50 on C and D. In my head the only way I can think to (mostly) guarantee no leaking (other than emptying the tank) is to keep the device upright open/close the top-fill opening every minute or so until at 10k feet or so to let the internal tank pressure match that of ambient, but this seems like a hassle.
Anyone with air travel experience with the TFV4 care to chime in? Thanks in advance!
