i only have one PV, but i always have 3 different flavors going on my two batts and PT.
i keep a cart filled for each of my juices so they're ready to go at all times. i'm still playing around with different levels of nic, and as delicious as they are, i get bored with just one flavor after a while. there are some juices that i vape more than others, but it's good to change it around from time to time. i just switch out the attys (1 for clove, 1 for TV's AC, 1 for fruity juices and 1 for "warmer" flavors like English Toffee, French Toast, etc...) accordingly.
I keep my 5v GLV loaded w/ a combo of Tasty Vapor AC/Ms. T's gingerbread (best flavor combo I've found!)
off to go order Ms. T's gingerbread...
