I usually line up a couple of RDA's with different coils and swap them as I go. I know its not that simple with the reo because of the bottom feed.
Yip, that's a nice way of going mechanical.
I've been juggling for the six months that I've been vaping, between buying gear, replacing gear and getting through trying all the premium juices available here.
But hopefully this year I can get a few PV's going and give mechanical a looking into.
