It's an acquired taste ! You have to acquire one to develop the taste. It is actually pretty simple, use any battery you have above 15A, build your coils above 0.3 ohms to be safe (tho I've used 0.25 coils with 20A batteries in them without problems). The bottle issue.....well, you just have to get creative but there are choices.I still don't grok the pico-squeeze love.. It's not regulated, it uses that idiotic proprietary bottle system.
I definitely could learn to love a squonker that size that was regulated - drop in pocket.. Or even like an NC, plus room for a silicone bottle.
