Need opinions on 18350 Tube mods with side switch or mechanical bottom switch. I have a Ratank from DFW vapor, and I would like to mount it on someting smaller than a lavatube, Bolt with extension. I have several 18350's so I would like to find a short one, don't want variable voltage, I usually wrap my coils 1-1.3 ohms, so vapor production is not an issue. Just lookin for low profile, and don't want to spend well over 100$, any input would be appreciated.
