So lately I have been switching between Suicide Bunny O.B. and Evaporated's Blue Sky, B@#tch! For my taste O.B. needs to be vaped at a much lower voltage than BSB, but for the life of me I cant remember to drop the volts when I switch tanks. I manage to ingest 2 awful tasting inhales before I catch on. I'm just getting too old for technology I guess.
