I've been using the Subtank Mini since just after they came out... I have 2 complete OEM tanks and 3 bell caps, 2 of the v1 bases and RBA coil heads, and 3 of the v2 bases and RBA units.
I don't really have a preference between v1 and v2... set wide open, the v1 bases are, to me, just as adequately "airy" as the v2 (which has two air slots instead of one); and, wicked correctly, the v1 RBA heads work just as well as the v2.
I do short direct lung hits, make ~2.5mm coils, at ~0.5-0.7Ω, use Ko Gen Do cotton, and rarely go over 22w. Decidedly middle-of-the-road, eh?
Always on the search for "a better way", I found a 3 minute vid that shows basically how I already do the v2 RBAs. The captions are in French, but there is no talking (and none needed), just a Jazz instrumental for background.
This is hands down the best youboob vaping how-to video I've ever seen, if only for it's conciseness and brevity:
It frustrates me to no end to have to sit through 15, 20, 30+ minute vids of redundancy, repetitiveness (see what I did there?

), and rambling narcissism , just to be able to glean about 3 minutes worth of usable information... so I don't watch those anymore - at all.
Got to hit the ground runnin' today, so catch ya later...
Y'all have a nice day
